[Pyusb-users] pyusb interrupt transfers & threading

[Christian N. <ma...@ma...>]

Hi list,

I currently have a problem with threading & pyusb interrupt read
transfers.

My testapp has a thread that 'polls for interrupts' (ahem. but seems a
libusb issue ;)). The mainapp only does some tests with the USB-device.
Simple 'Hello World' things.

It works so far except one thing: every time i call time.sleep() in the
main app / main thread, and the poll thread waits for an
interruptRead(), the time.sleep() never ever returns. Uh. Bad thing.

Any ideas? I could send my code, but i think it's quite useless without
the proper usb hardware....

I tracked the problem a bit, and it seems to be connected to the
interruptRead() call. If this call is replaced with a simple
time.sleep(), the time.sleep() from the main thread works as expected...

Any hints where digging / continuing ?

Thanks,
	chris
