[Libusb-win32-devel] Sutter?

[Black M. <bla...@ho...>]

Hi, im new to using libusb, but under windows I tryed the following code

int readval = usb_bulk_read(udev, 0x83, buff,64, 10);

(yadayadayada, some other code that has a timeout of 10ms)
And.. it causes my whole PC to 'stutter' even winamp has audio suttering 
artifacts. Thread was started with 'THREAD_PRIORITY_IDLE' and while it 
doesnt affect all mp3's it sure screws up alot of them, even tho I have a 
giant 300ms buffer set in winamp. So basicly I was wondering was A: is there 
a way to prevent this stuttering. B: is there a way to see if a read is even 
avilable before doing an actual read request? my device rarely sends 
packets, but when it does they have to be received asap. Iv commented out 
that line and the stuttering goes away. I realise this may be a problem with 
the win32 port of it, but I think an 'isdataavilable' sorta function might 
help in the core API. (Please don't use my nameing, I suck at nameing 
things!)
