hi, I have an IR interface with serial port and usb adapter... i have no
serial port so im tryiing to use it with usb and python...
my problem is that i cannot do anything xD
I tried do this:
*import usb
for bus in usb.busses():
for dev in bus.devices:
if dev.idVendor==0x4fc and dev.idProduct==0x201: IR=dev
>>> IR.open().detachKernelDriver(IR.configurations[0].interfaces[0][0])
Traceback (most recent call last):
File "<stdin>", line 1, in ?
usb.USBError: could not detach kernel driver from interface 0: No data
available
>>> a.open().claimInterface(a.configurations[0].interfaces[0][0])
>>>
>>> a.open().bulkRead(a.configurations
[0].interfaces[0][0].endpoints[0].address,30)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
usb.USBError: could not detach kernel driver from interface 0: No data
available*
after bulkRead dmesg throws
*usb 1-1: usbfs: process 4886 (python) did not claim interface 0 before use*
and I dont know what i can do
mi kernel : 2.6.22
im using Python 2.4.4
the IR interface is kosmos if anyone knows it...
thanks
