Hi again.
I'm having trouble communicate with my device. Device has a HID firmware
loaded and USB communication works if I use a program supplied with the
firmware.
Of course I want to write my own Python program.
After the interruptWrite function I get this error
*Traceback (most recent call last):
File "<pyshell#48>", line 1, in <module>
handle.interruptWrite(1, [1])
USBError: usb_submit_async: submitting request failed, win error: The
parameter is incorrect.*
Google didn't help.
What's wrong? What causes this error? I'm totally stuck. Here is my code.
Thank you.
import usb
bus=usb.busses()[0]
devices=bus.devices
for device in devices:
if device.idVendor == 0x04CC:
PowerModule = device
config=PowerModule.configurations[0]
handle=PowerModule.open()
handle.detachKernelDriver(0)
handle.interruptWrite(1, [1]) << Here I get the error
