UHS3.0 does this on the K66... You still will get a "wait" while enumerating, but it's fine after that.
The reason it has to "wait" is because it's doing a lot of work.
https://github.com/felis/UHS30
Also supports the SDcard on the 3.6 too, with just one simple modification... connecting the card detect line.
Why Paul didn't do that, I dunno, but it is a whole lot better than polling.
Sadly, this solution doesn't seems to work on Teensy 4.1. Back to the drawing board.Originally Posted by yeahtuna
That is sad - though not unexpected. Not that TeensyThreads isn't a well done impressive piece of work as far as it goes. Just that parking a task, as it is designed to do, seems fraught with peril for certain types of 'tasks'.
It is great that it assures timely attention for critical tasks - from those that can handle extended interrupts.
It's particularly frustrating when it works on one platform and not not the other. Today I rewrote the USB drive begin() function as non-blocking. It takes care of the system hanging when first opening a drive. Still need to implement the find partition part, but shouldn't be too much trouble.
I found an issue with some USB Flash devices, and I'm not sure fix it. Apparently some devices with issue a STALL when you request getMaxLUN(). In that case we need to reset somehow, and I'm not entirely sure how that is to be done. Currently, if I request max LUN on that drive, the Teensy crashes, so for now I'm just skipping that request entirely.

This is something that I knew about and played with for quite a while. I never had an mass storage device available that had more than one logical unit number or would cause the device to stall. When you say it crashes do you mean that it hangs? Have you tried turning debug on to see where it crashes or hangs? It would be interesting to see what the debug output is.I found an issue with some USB Flash devices, and I'm not sure fix it. Apparently some devices with issue a STALL when you request getMaxLUN().

There are a couple of things you can do to try and overcome the issue. In mscInit():
You can uncomment 'delay(500)' to see if that helps. I have seen some examples of this being used. Also uncomment the 150 ms delay after the call to get maxLuns. Lastly try commenting out 'msStartStopUnit(1)'. This also has been known to cause some devices to stall.Code:msReset(); // delay(500); // Not needed any more. maxLUN = msGetMaxLun(); // msResult = msReportLUNs(&maxLUN); //println("maxLUN = "); //println(maxLUN); // delay(150); //------------------------------------------------------- msResult = msStartStopUnit(1); msResult = WaitMediaReady(); if(msResult) return msResult;
If you know where it is hanging, try adding a timeout and then issue another 'msReset()'.
Again, I do not have any devices available to me that exhibit this issue
@Paul - Does the EHCI driver automatically clear endpoint stall conditions? It's been a long time since I looked at this. It looks like halted pipes might be handled in 'followup_error()' function.
I'm pretty sure it does. The crash I was experiencing comes from a bug, which is fixed in the code below:
Code:void USBFilesystem::end(bool update_list) { mscfs.end(); //if (update_list) device->filesystem_assign_to_drive(this, false); <-- Crashes the system if device isn't set if (device && update_list) device->filesystem_assign_to_drive(this, false); device = nullptr; }
Hi, I manufacture a board since few years, I first started with Teensy 3.2, last year I had to update to Teensy 4.0 due to lack of stock, so I think that the hard work was already made and the possibilities of new hardware are greater. Now my client ask me for data download to PC in USB instead of expensive GPRS o Ethernet external modules, so I give a try to Teensy 4.1.
With Teensyduino 1.57 I managed to read and write files, but I have problems with some usb drives, is not a option to buy the same unit, final customer will use any stick.
After trying few different drives there are some common symthoms:
- USB 3 drives use to fail in a high %, some are even not detected.
- Some of the other units fail to detect, the firmware hangs and as I had set watchdog the unit reset and after the reset with the stick plugged it works.
-Sometimes the teensy hangs just after connect the stick so maybe a current comsumption higher than expected.
-A couple of units detected but unable to write on it, after changing to GPT from MBR and reformated it works, all tests with FAT32 partition.
My tests was with low capacity drives, 16 to 32GB.
Even with included sample scripts the same unit works with one script and not with other, Listfiles work but can't write.
I am able to test anything to help if these problems are already detected and you are working on it.
Anything just comment and I will do my best.
Regards
Please follow the forum rules and show code.Always post complete source code & details to reproduce any issue!
The code is based on the one posted by wwatson here, this fails too.
As I mentioned before problems occurs with sample codes of teensyduino with the same sticks that fails in my script so I think must be a library problem related with different hardware or MBR/partitions types.
2 different sticks, others doesn't even initialize.

I've spent weeks going over the MassStorage code and have pointed out several issues, but the maintainers of the code haven't attempted to fix them. Some of the issues are very simple fixes, others are much more involved. The code is complicated and working on such low level hurts the brain. Just to get things working at the level they do is quite a feat. Making a small change to the code involves a huge amount of testing and is very time consuming so I can understand that there's a lot of resistance to making changes. Until proper fixes come to the library, I don't think you should rely on it.
I've resorted to hacking my way to making it work for my needs, but even after my weeks of work there are times when things don't behave quite like they should, pointing to issues deeper down in the USBHost library. Much like the maintainers of the MassStorage driver, I've gotten it to work well enough for what I need to do, but have come short of getting rid of all the issues because there seems to be ghosts in the machine and tracking them down will lead to pain and suffering.
Let's see if we can figure out what is going on. First I assume you are using Arduino 1.8.19 along with Teensyduino 1.57. Next USB 3 drives have not been tested as the T4..x supports USB 2.0. Make sure the drives are formatted FAT32 or EXFAT. Again some thumb (stick) drives can take some time to initialize and become ready. Up to 30 seconds or more. In USBHost_t36.h at about line #63 you will see a commented define like this:
Uncomment this define and compile the "driveinfo.ino" example file and upload it to one of the failing drives. Then you can copy and post the debug output. This will give us more of a chance to find out if and why it is failing.Code:// Uncomment this line to see lots of debugging info! //#define USBHOST_PRINT_DEBUG
One other thing you can try is increasing a couple of timeouts in "utility/msc.h" file starting at line #73.
From:
To:Code:// These two defines are timeouts for detecting a connected drive // and waiting for it to be operational. #define MEDIA_READY_TIMEOUT 1000 #define MSC_CONNECT_TIMEOUT 4000
I have a SSD drive that needs the timeouts to be 5000. Lastly, make sure the drive is not write protected.Code:// These two defines are timeouts for detecting a connected drive // and waiting for it to be operational. #define MEDIA_READY_TIMEOUT 5000 #define MSC_CONNECT_TIMEOUT 5000
There have been changes made since Teensyduino 1.57. I would suggest updating to TD1,58 Beta 2.
We really need some debug output to try to help.
Edit: If you can, please give some information on the thumb drives that are not working

@yeahtuna - Yes, I am leery of putting in PR requests for issues that I cannot duplicate. A lot of people and myself have put in countless hours testing and updating this library. Many devices have been tested and proven to work. Only with good debug output and examples of the failing code being used can we begin to track down issues...

Sorry, I am not sure who the "maintainers" are?
The only person who can merge in any changes to this library is the Paul. @wwatson, who did most of the original MasStoreage work, has been very active on this thread and project. A few others of us like @mjs513 and myself, have done some of the intermediate glue work, @defragster has helped with a lot of the testing...
But it is up to Paul to decide when and of things will get merged in. And needless to say, with all of the chip shortages and the like he has had his hands full with other things, like having boards to sell.
With some of this functionality and libraries, there are areas where Paul needs to decide on how certain things will be changed. For example, extensions to FS.h to support things like File system notifications (when is a CD installed), who notifies MTP when an underlying file changes. How does the sketch know when files were changed on the host over MTP... So, I personally am off playing on some other unrelated stuff. But at some point, will likely jump back into this.
Suggestions: If you do have some simple obvious fixes to the library, create a github Pull Request, with the fix. If it makes sense, you may want to @<some of us> into the PR, such that we might, try it out and comment.
As for more complex changes, or architectural changes like using threads or RTOS and the like, I might personally agree in several cases it would be nice. But...
Good luck.

Do you have any links, for example on Amazon for some of these drives?
Preferably ones that are pretty cheap?
I've bought some cheap PNY 2.0 16 GB drives, same model in same order and evey one have different chipset, so that won't help, the one that doesn't initializes is an old Kingston Datatraverler G2, difficult to buy I think.
I made test with every stick I've found.

Did you ever try changing the timeouts in post # 638?I've bought some cheap PNY 2.0 16 GB drives, same model in same order and evey one have different chipset, so that won't help, the one that doesn't initializes is an old Kingston Datatraverler G2, difficult to buy I think.

I did have a PNY 16G that magically became write protected and never was able to undo the write protect...Code:// These two defines are timeouts for detecting a connected drive // and waiting for it to be operational. #define MEDIA_READY_TIMEOUT 5000 #define MSC_CONNECT_TIMEOUT 5000
Note: I looked up at amazon, and they have a few Kingston Datatraveler G2 drives, but none look like the one in picture. So not sure if they would be apple to apple...
And if they are all different not sure worth picking up any as may not reproduce the issue you have. Also if the ones that have issues are no longer available, then harder to get motivated...
Yes same results.
Thank you
Indeed it doesn't worth you time, very old unit, I'm testing with 1.57 Beta 3 and results are differents, I will try get somo logic in the errors.
Thank you all for your efforts.
I found this:
https://www.tigerdirect.com/applicat...?EdpNo=4433961
But they are out of stock. I am really curious as to what the problem is. The only time I have seen the tag errors was when I was trying to run MSC without checking for transfer completion. But with all of the thumb drives I have tested only one Sandisk 8G and a PNY 16G failed. Both of those write protected them selves. The biggest problem I saw was with the amount of time it took for some drives to become available. Some hard drives took up to 30 or more seconds to become available. Also had to increase the timeouts for a Targus SD card reader I have. Lastly the Kingston 120G SSD drive had problems with the default timeouts...
I did have a PR in for increasing the timeouts but I don't see it now...

Hi, appart of this old Kingston Datatraveler G2 that doesn't even initialiaces, I have 2 Sandisk 32 GB that I get CSW Tag Error: 253, one is this SDCZ48-032G and the other is SDDD2-032G-GAM46
