What are the steps that reliably reproduce the problem?

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,...

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...

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.

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...

Hi @edemers

First off -- cool project!

In principle,...

... 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...

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...

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...

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,...

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...

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:
...

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),...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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: ...

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...

You really should update the site and the email template then!

Although small orders are not in themselves major profit makers,...

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...

Hi Paul or Robin:

In the shopping cart step3 page, the Shipping Method details says that US Priority Main does not include tracking.

Yet...

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...

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...

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://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:...

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"

......

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...

Do you have a specific thread in mind? Note that I'm asking about device mode, not host mode. That is, Teensy as slave to PC (like it "normally" is), not Teensy hosting other devices.

Hi all,

Could somebody tell the current status of the/a High Speed USB driver for Teensy 3.6? I.e.: for device mode on the installed micro-USB connector.

Thanks -- Graham

Hahaha thanks for the link. One way it's relevant is that the Cortex M3/M4 book I bought last week on Paul's recommendation will soon be obsolete. Doh! I knew that would happen.

Anyhow, in that...
