DigiCDC on Win10 (blue screen)
« on: September 10, 2016, 08:19:38 am »
Hello,

Since hours, I'm trying to get this serial over USB libary working on a Win10 x64 PC, using the latest Arduino 1.6.11 IDE and a digispark (attiny85). Other sketches than DigiCDC/serial compile and work fine. I have a digispark with DigiMouse lib code sending mouse messages to this PC, that works.

When I try to load any DigiCDC basic examples (echo, read, LED, print), my Win10 computer crashes just after download, when the attiny85 starts the sketch. I each time get a "Sytem Thread Exception Not Handled (lowcdc.sys)" blue screen.

I noticed lowcdc.sys was recently updated for Win10 x64. I installed that version, but it still crashes, the same way:
https://github.com/protaskin/LowCDC-Win10x64

Are some extra steps known to get this DigiCDC/lowcdc.sys driver working on Win10 x64? I didn't find anything so far.

Would my PC behave the same with Digispark Pro, which is ATtiny167 based? Both 85 and 167 have 512 bytes of SRAM, CDC LED example sketch uses 214 bytes...

Best regards

Siana

Well it works for some other person who replied you on GitHub. But it also doesn't work for me, same issue. I experience BSOD with SYSTEM_THREAD_EXCEPTION_NOT_HANDLED in lowcdc.sys. Is this the same issue you're experiencing? In my Event Log category System, I find the following message:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x0000007e (0xffffffffc0000005, 0xfffff80d9a9255a6, 0xffffb58149745ab8, 0xffffb581497452e0). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 20685e0b-44c2-4376-87e1-a55162c8882e.

I wonder what could be the culprit? Perhaps some other software, like chipset-specific drivers?
I've got AMD based mainboard with 760G and SB710 chipset, which reminds me, under prior versions of Windows, a USB filter driver was installed that fixes performance issues of bulk or isochronous endpoints, while under Windows 10, I have no longer seen it. I also have a signed version of hidusbf.sys (mouse overclocking driver) installed, which I wonder if might interfere. The board also employs a VIA xHCI USB3 host controller, correspondingly its drivers are installed, however I have used USB2 port in this instance.

If it works for some people but not for others, we need to start looking at what's common and what's different between these cases.
