I am setup for testing now. @mjs513 I am getting the same results as you. Everything seems to be working except un-plugging and replugging the flash drive. I can't remember, but has a powered hub been tried?

@KurtE - Had a chance to play with the MTP sketch. Some interesting results when playing with write sizes. Kingston DT50 32G, 512 bytes at a time: Start write file: write_test_file.txt length:1048576 Write Size:512...

@KurtE - that worked. Thanks. Want to test some hard drives as well. They are always faster but probably not practical for remote applications.

@yeahtuna Incorrect - at that point no SCSI command has been called...

@KurtE - Linux Arduino 1,.8.19 TD1.58B3 - Downloaded MTP_TEENY-MAIN.zip. Setup T4.1 and uploaded. All good. Then selected: store:2 storage:30001 name:MSC0-126GEXFAT fs:200030cc Ran this: w 1048576 512 test.txt The...

@KurtE @mjs512 - Decided to just comment out "msReset()" call. Updated my version of USBHost_t36 with @PaulStoffregen version and did a PR for it and extending the timeouts defined in "msc.h". Glad to see a lot of...

Thanks for testing:) I'll test more of my devices and issue an appropriate PR.

I have a few things I have to do this morning so after that I want to test more devices SD card readers, Hard Drives, etc. Just to make sure msReset() is not needed. For the most part I am convinced it's not needed. I...

@ All - In mscInit() function, comment out call to msReset() function: // Initialize Mass Storage Device uint8_t USBDrive::mscInit(void) { #ifdef DBGprint println("mscIint()"); #endif uint8_t msResult =...

@KurtE @mjs513 - Here is a web article of interest with information on stalled USB 3.0 pipes and how to reset and clear them: http://billauer.co.il/blog/2019/12/usb-bulk-overflow-halt-reset/ Would like to adapt...

I have a magnifying lite and a magnifier for just such an occasion:) It states that it is backward compatible with USB 2.0. I think it's time to do some online research... Edit: Here is a link to the support page for...

@mjs513 - I also noticed a couple of other things in those snapshots. Down a couple of lines you see "URB_FUNCTION_SYNC_RESET_PIPE_AND_CLEAR_STALL" twice. I think this is what we are seeing on the T4. For some reason...

@KurtE @mjs513 - A little progress:) I have stooped to single sector reads and writes. Here is a sketch that appears to be working: #include <Arduino.h> #include "USBHost_t36.h" // For this sketch we need to define...

@KurtE That makes sense. 13 bytes is the size of the CSW and probably why we are seeing: USBDrive dataIn (static): 0 ERROR Followup I think. But why... Missing something. Working on that right now.

@KurtE and @mjs513 - Referring to post #664, the command code is indeed the SCSI write(10) command, Instead of showing the tag error first I need to check the CSW status byte bit 0 first and if not 0 do a request for...

Not yet:( Just got home from work. Will play a little more tonight. Looks like I am going to have to go into the lowest levels. Try a single sector write and see what happens. It's complaining about an unrecognized CBW...

Not yet:( Just got home from work. Will play a little more tonight. Looks like I am going to have to got into the lowest levels. Try a single sector write and see what happens. It's complaining about an unrecognized CBW...

Ok, have narrowed it down to a failed command error. Bit 0 is set in the CSW status byte. Possibly a command not recognized by the USB stick. See below: msWriteBlocks() msDoCommand() USBDrive CallbackOut (static)...

@mjs513 @KurtE - Just got my drive and tested. Same results as you guys. Going to start walking back through the different versions of TD to see if anything changes. Beings how this only seems to happen with these...

@mjs513 - Just tried using Windows to compile "DriveInfo.ino". This is with a Kingston 128G USB stick. Fist time: Waiting for Drive to initialize... === Task() Drive 0x200035e0 connected === >>...

It does look like there is no response but this: transfer->qtd.token = 64 does not make sense. CSW size should be 13 bytes if I remember correctly. not sure where the 64 bytes are coming from. I should be getting my...

I'm getting the same. Up the road a piece in Washington state...

Can you post the sketch you are using that causes this error? We can only guess at what is causing the error. Right off the bat it looks like it is trying to access POSIX style file functions which Teensyduino does not...

Will be 70 and retired in November:) And you are right, It does keep the brain sharp...

Glad you have it working. I am running under Linux and I also had to un-mount and re-mount the MTP drive to get an updated copy of the directory listings. I seem to remember that @KurtE had a way of refreshing it from...

Yeah, I think I mentioned that in an earlier post. My curiosity gets the better of me as well:)

@sbfreddie - Been working with the sketch in post #10. First off is this what you are trying to accomplish: ************************************************ destinationSDCardDir =...

I have ordered up SDDD2-032G-GAM46 from Amazon. Should be here this coming Wednesday. I'll check it out then...

I found this: https://www.tigerdirect.com/applications/SearchTools/item-details.asp?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...

Did you ever try changing the timeouts in post # 638? // These two defines are timeouts for detecting a connected drive // and waiting for it to be operational. #define MEDIA_READY_TIMEOUT 5000 #define...

@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...

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...

Missed that one I guess... Thanks:)

Thanks for the reply:) It really is a bummer...

@MultipleMonomials - I see that USB Host was supported with Mbed 2.0 with LPC1768. But I cannot find any thing in Mbed-CE. Has this not been added in yet? Thanks...

@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.

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...

In the USBHost_t36 library find hid.cpp. make sure line #253 is commented out: void USBHIDParser::out_data(const Transfer_t *transfer) { //Serial.printf(">>>USBHIDParser::out_data\n");...

@Paul - I agree. It takes a lot of time to filter through all of the directories and layers of the code. And I also have seen that they are using the one byte at a time packets. I have a general idea of there layout and...

Well, the best times I can get for USBSerial is about ~3600 lines per second with this: #include "mbed.h" #include "USBSerial.h" uint32_t counter; uint32_t prior_counter; uint32_t prior_clock; uint32_t...

Well I finally caught up with you guys... With all of the changes from post #76 and #82 and the following CMakeLists.txt: # # Mbed CE Hello World Project # cmake_minimum_required(VERSION 3.19) cmake_policy(VERSION...

I remember seeing that before. I will give it a try tomorrow. Won't have time tonight. Thanks...

@Paul - I'm not sure if this will help or if you have already run into this but I programed the T40 after setting "target.console-usb": true in mbed_app.json. It failed to communicate but there were no death flashes...

@MultipleMonomials - Setup mbed-os master branch. The 'Hello World' example fails. Blinking orange LED. This is after the merge. I am also still getting the link error seen in post #34. missing space before the '=' in...

Review done. Finally have example(s) working under W11. Little more hair pulling than with Linux but very similar procedure wise...

That's good to hear:)

Got it figured out:)

Yup, just downloaded it from your link and got the same message when I tried to run it. Sorry, It has been quite a few years since I have used windows. Windows 7 was the last one I used. EDIT: I'll keep trying...

No, it says window defender has blocked the install. I tried disabling it and it still came up with the blocking message... I sent a PM as well. I take that back, it does say: Microsoft Defender SmartScreen prevented...

OK, I am trying to go through the windows install procedure. Got to the download ninja part. Defender stops me in my tracks. It's not recognized. Tried turning off defender. No go... Any advice?

@tstarr - There have been changes made to USBHost_t3 library. I would suggest that you upgrade Teensyduino to 1.58 Beta3. Here is tthe link: https://forum.pjrc.com/threads/71693-Teensyduino-1-58-Beta-3 This is the...

Did you see this notice for that repository: UsbMscFat Library NOTE: This Library is OUTDATED !!! Please Use the examples in the latest USBHost_t36 stable library for the Teensy. Teensyduino 1.57 up 1.58B3. Arduino...

With the information you've given us there is not much we can do to help you... Please read the Forum Rule above. What operating system are you using? What version of Arduino and Teensyduino are you using? What are the...

Thanks, Others distractions are sometimes needed to clear the head:) I downloaded your RawHid repo and I'll start there...

Thanks, That points me in the right directions:) I found this https://github.com/KurtE/RawHid. I think this is what @Kurte referred to in the off topic post.

That is a actually a good idea but there are times when different types of devices (particularly older thumb drives) can a few seconds to do internal housekeeping. Usually flushing the internal buffer. So I as well am...

Glad it helped. I have another project that I am trying to get finished as well. I just keep distracting myself:) I have been playing with SerialTransfer and USB host serial. I have one T41 sending and receiving ...

You can if you would like to. I hope to get more time to gain experience with this. I am on vacation right now so I have some time. But I cannot guarantee that I will be able to work though it in a timely manner:)

@anybody interested - Here is the first go at documenting the installation and usage procedure for MBED CE on the Teensy T40. May try to set it up on Windows 11 (maybe). MBED CE OS installation instructions for...

Hi Paul - Me too. Based on the installation instructions, readme's and your post #28 I came up with the right sequence start to finish that seems to work. I have @manitou's post #32 working as well. Just tested the...

Thanks - I am new to Mbed and Cmake. I have a lot to learn. My bad:) Should have read all of the posts I guess...

@MultipleMonomials - I have everything setup and successfully built the hello-world sketch. But ran into an error during the Ninja build with the linker script: ...

I might be wrong, but as far as I know the T4.1 does not have a built in USB HUB which is what you would need to use those connectors. As @defragster stated above you just need an external USB HUB connected to the T4.1...
