Hey everyone,
I'm trying to write my first program with pyUSB. I have already figured
out how to identify my device, open it, add it to a handle, close it and
claim it's interface.
Here's my situation:
The kernel recognizes my device ( a linksys cit200) as a device already
and it actually shows up as a plughw device. The problem is the device is
not "activated" My question is, do I have to claimInterface this device
to send/receive signals to it? For now, I just want to see if I can
"enable/activate" it, so the mic/speaker will work on the thing.
Right now, in order for me to claim the interface, I have to
detachKernelDriver each interface (there are 4 of them, 3 alsa/sound, 1
hid), then setConfiguration, then claimInterface. In doing so, I lose ...
it showing up as those devices.
Example Code:
---------------------------------------------
import usb
# linksys CIT200 Device Info
vendor_id = 5041
product_id = 29
buses = usb.busses()
for bus in buses :
for device in bus.devices :
if device.idVendor == vendor_id :
if device.idProduct == product_id :
# found the CIT200
linksys = device
# open device
handle = linksys.open()
# setup interface and configs ... there are 4 interfaces for this device...
config = linksys.configurations[0]
interface = config.interfaces[0][0]
# detach kernel drivers
handle.detachKernelDriver(0)
handle.detachKernelDriver(1)
handle.detachKernelDriver(2)
handle.detachKernelDriver(3)
# set configuration and claim interface(s?)
handle.setConfiguration(config)
handle.claimInterface(interface)
handle.setAltInterface(interface)
---------------------------------------------
Any help would be appreciated. I will probably have a few more questions
to follow :)
Thanks
