Just building straight from cube IDE.

Using Full Speed device

Selected: ACM (1) HID Keyboard

Serial device /dev/ttyACM0 is not mounted Only keyboard:

if I enable only the ACM then I get it mounted as /dev/ttyACM0

This device has 1 bidirectional control endpoint0 • 3 IN endpoints (EPs) configurable to support Bulk, Interrupt or Isochronous transfers • 3 OUT endpoints configurable to support Bulk, Interrupt or Isochronous transfer

Is that the problem? Lack of end points? How do I verify this? I thought that ACM used 2 out 1 in and keyb 1 and 1 ??

Thanks And a nice job!

SPKR + MOUSE works

[fsartori66]

looks like this is a linux issue on windows10 it works

[fsartori66]

I was able to get it working: File: usb_cdc_acm.c 2170 desc[16] = str_idx;

Before was overwriting position 15 which correspond to the bInterfaceProtocol

That's great. earlier acm string descriptor was at 7 (IAD)

will update to 16 thanks
