aura-openrgb.usbdump
Somehow FreeBSD's usb stack doesn't seem to like this device:
ugen0.3: <AsusTek Computer Inc. AURA LED Controller> at usbus0, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (16mA)
The HID descriptors are readable, but communication fails.
https://gitlab.com/CalcProgrammer1/OpenRGB (uses hidapi->libusb) does not
manage to enumerate it (get firmware revision):
openat(AT_FDCWD,"/dev/ugen0.3",O_RDWR,00) = 5 (0x5)
…
ioctl(5,USB_DO_REQUEST,0x7fffdfdfc708) ERR#5 'Input/output error'
poll({ 3/POLLIN 6/POLLIN|POLLOUT|POLLRDNORM },2,-1) = 1 (0x1)
read(3,0x7fffdf9faf0f,1) ERR#35 'Resource temporarily
unavailable'
ioctl(6,USB_FS_COMPLETE,0x7fffdf9fae78) = 0 (0x0)
ioctl(6,USB_FS_COMPLETE,0x7fffdf9fae78) ERR#16 'Device busy'
ioctl(6,USB_FS_START,0x7fffdf9fadb0) = 0 (0x0)
Looking at the usbdump, after we send the firmware version query (shows up as
packet number 20 in wireshark, length 220, data with the EC 82 00 00 00 ..
bunch of zeros), what we get back is Error: Stalled, so that is why the I/O
error.
