Device Descriptor Request Failed #41

Closed yoft closed 1 year ago

yoft commented 1 year ago

Hi, I'm having an issue with windows and BTT SKR 1.3.

Everything was working fine previously, the machine had been turned off for maybe a week.

Now when I plug the usb cable into the computer I get a popup saying the usb device malfunctioned. In Device Manager it is labelled as "Unknown USB Device (Device Descriptor Request Failed)".

Is this a software issue?

I've tried 3 different cables, and the board is also currently sitting on the workbench completely disconnected, and now pwered from usb, I've also tried powering from the 24v PSU.

This was on a Windows 10 computer, I've also tried a windows 8 and got something similar.

Thanks,

Hard to tell - could be a dead MCU (unlikely since the board is detected?), windows driver issue, ... This is the driver used by my Win10 machine:

Are you able to reflash the controller?

Hi, SD bootloader still works, I tried renaming firmware.cur to firmware.bin, I assume this worked as it'd change back to .cur after powering it up. Is there any other information I can provide that will help? I appreciate your hard work!

Ok, this was with the same firmware used when it was working?

Since it worked a week ago and no changes was made to the controller it is either a new hardware problem with the controller or an issue with the Windows USB driver/stack. Is your USB driver the same as I have installed?

Yes, same firmware.

I'm starting to lean towards hardware issue. None if the driver information is available, on Windows 8 it lists everything on that page as either "unknown" or "not available". It's the same for all usb ports across two computers, I tried a brand new usb cable too, just to rule that out. I tried compiling a build with USB_SERIAL_CDC commented out, just to see if there was anything different. No change. Recompiled with it enabled again, still no change.

I've just tried using Smoothieware firmware, issue persists. I'm writing this board off. Thank you for your help!

When I set up the usb-serial adapter properly, I can connect with IO Sender! Looks like this will be the solution for now...
