Thanks Paul, I'm glad I asked! And I just now added a lockable T 4.0 to an Amazon order.

Is it possible to take a Teensy 4.0 Lockable version, and assuming it hasn't been locked, convert it to non-lockable? Motivation: On Amazon, no-pins T 4.0 is available, which has low price and Amazon prime fast and "free" delivery, but it's the lockable version. It would be a frequent...

Thanks for posting that... I got hung up on the same point. Google and lukexyz to the rescue!

@Etienne > Now that I can reproduce the problem at will its easy to provide you with info. What are the steps that reliably reproduce the problem? > Both working and none-working joystick setup use the drive filename usbccgp.sys I think that may just be the generic driver that comes into...

Hi edemers, The objective was to correlate a working or non working state of affairs with which blahblah.sys Windows picked for that joystick. It's a bit hard to tell from the info you posted, because I can't tell in which case the joystick was working. At any rate, previously I had come to...

What?! Progress? That's awesome! Kudos to Frank B for jumping in and knowing the right stuff! Annoyingly, it still doesn't identify the root cause though, unfortunately. @edemers Would you mind having a look at the USB entries for example with Nirsoft's USBDeview, and see if it lists separate...

OK, that's interesting. My previous questions (and Frank's idea too) were based on the idea that Windows might be saving, and later assigning, the driver based on VID, PID and also serial number. However, if other "new" joysticks (presumably with different Teensys and maybe different serial...

A question: When this problem strikes (you plug in one of your Teensy-based joysticks, and it doesn't work), if you plug in a different one of your joysticks that was never connected to that computer, does that one work, or does it fail too? I think we would make a step forward if we at least...

Hi @edemers First off -- cool project! > If the problem cannot be fixed, would it be possible to have an executable file > that would flush VID_16c0 out of the Registry In principle, maybe. Usually, adding, deleting or revising Registry entries would be easy to write an exe to do...

... and that other thread now has images of the PCB layers involved, and schematic detailing the exact damage caused.

Paul -- posting those PCB images on Christmas morning is really beyond the call of duty. Thanks! So here's my digested version. Here are the relevant layers of the PCB, with the "VIN" net indicated in orange. Click to enlarge. Note that as others have said on the other thread (Cutting Vin...

Just replying to this thread to link in a thread I started, not realizing this one existed. Paul request; Separate Vin/VUSB Teensy 3.2

Wow! MatixRat, that thread is a direct hit! Thanks! That indeed would explain what I saw. However, I would still like to understand the routing in that area. Ie: I'd appreciate if Paul was willing to share that section of PCB layout. Graham

Hi Paul and all, The short request to Paul: I know that while the Teensy schematics are available, you generally keep the Teensy PCB layouts proprietary. However, I've recently hit a snag where I need to know the PCB layout in this region of Teensy 3.2: ... because I'm trying to...

I realize this is a somewhat old thread, but in case others stumble in here: You might understandably find it inconvenient to have a floating wire connected to the Reset pad under the Teensy 3.2, when the rest of the connections to the Teensy are by header pins, allowing the Teensy to be...

Hi Paul, For my part, I made a backpack board specifically to be able to reattach the broken-off USB connector to this Teensy 3.1, in hopes of tracking down the problem further. When I then used Arduino IDE + Teensy Loader to program this repaired board, it still delayed almost 5 secs, but...

Probably no big surprise, but the fresh Teensy 3.2's work fine. No complaint of not responding to USB request to enter program mode.

And on a little more thinking, I remembered this post of mine regarding USB issues: https://forum.pjrc.com/threads/23566-Teensyduino-USB-Joystick-no-data-driver-problem-workaround?highlight=gwideman ... and noted that I have been misled once before into thinking that USBDeview deletes all...

Hey, thanks for the comment!

Paul -- thanks for your detailed commentary! Question: Is there some doc for the list of values in the reboot Status message? It's so odd that, as I reported, on the same machine (Computer A), just minutes apart, a Teensy 3.6 behaves just fine (no appreciable delay to complete the reboot). I...

All these years and somehow I never knew about that feature! Thanks! As it happens, Teensy Loader was still open, so here's an excerpt showing an attempt to program the Teensy 3.1. The key aspect is the sequence of "status read, retry" messages, 49 of them, before the message "Teensy did not...

Teensy 3.1: "Teensy did not respond to a USB-based request to enter program mode." I have seen a few previous threads on this subject, but none seem to quite apply. The main symptoms: Using: -- Computer A as host, Windows 10 Pro -- Teensy 3.1 -- from the Arduino 1.8.13 environment --...

Thanks for pointing out that kind of product. Obvious when you know!

I have my project running nicely using T 3.6's built-in micro SD card, and using a version of play_sd_wav library (revised to include 11k, 22k, and seek). But for user convenience, I need to provide a full-size SD card slot, with spring eject mechanism. I'm a little confused on the best way to...

Who exactly is going to be helped by documentation that is incorrect? What possibly pedagogic purpose does that serve?

Hi all, but mostly for Paul, or at least his vast documentation department :-), Regarding page: "Wire Library" https://www.pjrc.com/teensy/td_libs_Wire.html. There are a couple of serious problems with the sample code on that page, such that someone following that code will end up in a...

Thanks again, very useful.

Paul -- I wonder if you have example test wav files that have the "features" that necessitated the STATE_PARSE4 and STATE_PARSE5 strategies to "ignore extra unknown chunks" (presumably after fmt) and "skip past junk data before fmt header"? I'm trying to refactor the code to make "reading the...

Thanks Paul, that was very helpful, especially your thoughts on the slower data rates. And of course, it's understood you're chronically overloaded with other developments and support. For readers following along: The "memory sample player" that Paul refers to is play_memory.h/.cpp. Its...

Hi all, but probably for Paul: I've been studying the internals of play_sd_wav, and have a pretty good grasp on what it does. However a few points are puzzling: 1. Several combinations of data rate and mono/stereo are not implemented. All the "CONVERT" ones for 22k and 11k data rates, for...

Perhaps this is the mentioned seek implementation? https://github.com/mxmxmx/eurotrash_mkII/wiki/hacking

Thanks for the reply. If some people have implemented seek in the raw player, I'd be interested in seeing that, if someone could point me to it. Yes, one "tape side" readily fits on an SD card, however an example book I'm targeting has 50 such sides -- so using raw mono that's 12GB or so...

I am looking at the feasibility of using Teensy 3.x with Audio and MP3 libraries as the basis of an audiobook player. (An audiobook player that would be tractable to users who have some cognitive or physical limitations -- hence the interest in a hackable platform to make specific physical UI.)...

bigpilot: You might find something useful in this thread regarding Windows USB HID: https://forum.pjrc.com/threads/23566-Teensyduino-USB-Joystick-no-data-driver-problem-workaround?highlight=gwideman

Hey, where's the "Like" button for this?:D

Thanks Paul for jumping in with that -- very helpful to know. Do you happen to have any technical references for the improvements to enumeration? I see that this Microsoft page leads to "What's new for USB" pages for Win 8, 8.1 and 10...

I have to add a big cheer for the article Paul wrote capturing this whole experience and a whole lot about some nitty gritty details of USB data structures and protocols: https://www.pjrc.com/usb-hub-bug-hunting-lessons-learned/ I'm guessing Paul reported the issue with Beagle's software to...

Thanks for raising this issue.. I hit it too. Windows 7 (the best one :D )

I am VERY disappointed. After carefully selecting a shipping option that guaranteed a lack of tracking, and then receiving an order acknowledgement that further confirmed a tracking-free order, I received this email: "Your recent order with PJRC was shipped today by Priority Mail delivery...

> You get tracking with both priority and first class packages. You really should update the site and the email template then! Although small orders are not in themselves major profit makers, getting customers to order at all is facilitated by putting as few speedbumps in the way as possible...

Well I just ordered using Priority. The auto response email (from auto-Robin) says Your package will be shipped by: "US Priority Mail" This is a low-cost service which does not have tracking. We will send you a message when the package has shipped, but there is no way to track the package...

Hi Paul or Robin: In the shopping cart step3 page, the Shipping Method details says that US Priority Main does not include tracking. Yet https://www.usps.com/ship/priority-mail.htm#legal-disclaimers--definition--4 says Priority does include tracking, at least if you ship online or at retail...

Thanks for that response. If you're going to say something antagonistic, you might want to consider whether your assumption is true. I see that you frequently contribute in a positive way, so I'll assume you were just having a cranky moment. ... because doing something by yourself is the...

Paul and KurtE: Thanks tremendously for your fast and very informative answers (and of course for the work on Teensy and the libraries). Regarding the keyboard nuances mentioned by KurtE -- thanks for elaborating, very useful. Expanding slightly regarding 3.5 vs 3.6, for benefit of future...

I wonder if Paul or someone could update on the current status of the USB Host library for models of Teensy with second USB port. 1) The USB Host library is the one here, right? https://github.com/PaulStoffregen/USBHost_t36 2) Does this work on the Teensy 3.5 as well as the 3.6? I ask because...

https://forum.pjrc.com/threads/45916-Teensy-3-6-VGA-driver/page3 for those following along at home. Fun experiment!

Yes, as I have done here: https://forum.pjrc.com/threads/23566-Teensyduino-USB-Joystick-no-data-driver-problem-workaround and here: https://forum.pjrc.com/threads/46208-Bug-in-delayMicroseconds-25-too-short-for-const-delay-lt-64us ... small contributions I know, but focused and get to the...

OK, thanks Paul for clearing that up definitively. I guess I was misled by reading about the 480 Mb/s somewhere, for example in the quickstarter page: "USB High Speed (480 Mbit/sec) Port" ... which I guess is not wrong per se... it's just not the port with the connector already installed. I...

Yep I'm asking about prospects of the plain ol' installed USB connector running at High Speed 480 Mb/s when talking to PC (or other computer) host.

Yeah, I know all that. Like I said in the original post, I'm looking for the HIGH SPEED feature (480 Mb/s) that Teensy 3.6 has the hardware for, not the 12 Mb/s. I'm interested in the Serial over USB interface, but if the driver(s) support HS, then I'd guess all the interfaces would be capable...
