usb.core.USBError: [Errno 32] Pipe error

See original GitHub issue

Hi Charlysan, I’ve install you library and trying to run it failed :

root@orangepipcplus:~/pyrfidhid-master# python examples/read.py 
Initializing device...

I’ve also tried on my own desktop, and it is failing with the same stacktrace … Any idea ?

@lhlong, sorry for the delay; I missed your last post. I’ve been using pyusb 1.0.2. Same question for you, does your device work with IDRW v3 windows app?

I’m closing this issue as all the errors described above seem to be related to unsupported devices. I’ve included better error handling in version v1.1.4, so you should see now a more verbose error message for any core.usb.USBError exceptions.
