Hi Folks,
USB newbie here. I'm trying to (understand and) read data from an
interrupt endpoint:
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x81 EP 1 IN
bmAttributes 3
Transfer Type Interrupt
Synch Type None
Usage Type Data
wMaxPacketSize 0x0008 1x 8 bytes
bInterval 8
using:
print dev.read(0x81,8,0,1000)
But I'm getting timouts every time, no matter the timout setting. As
I'm still learning USB I'm guessing I misunderstand (most of it)
interuppt endpoints.
busdog shows me that the native software reads 2 bytes device every 60 seconds.
Any help would be...helpful and much appreciated.
Thanx,
D
