A project log for USBShare.exe

Replacing unknown exe with opensource

import usb.core
import usb.util
import usb.control

# find our device
dev = usb.core.find(idVendor=0x1a86, idProduct=0xe041)

# was it found?
if dev is None:
    raise ValueError('Device not found')

# usb.control.set_configuration(dev, 0)

bmRequestType = usb.util.build_request_type(usb.util.CTRL_OUT, usb.util.CTRL_TYPE_STANDARD, usb.util.CTRL_RECIPIENT_DEVICE) #// should be 0x00
bRequest = 0x09
bConfigurationValue = 1
wIndex = 0
wLength = 0

dev.ctrl_transfer(bmRequestType, bRequest, bConfigurationValue)
dev.ctrl_transfer(bmRequestType, bRequest, bConfigurationValue)

Doesn't work though. PyUSB sent out a message that was 64 long instead of the 36.

Unless that is libusb doing the padding, IDK.
I don't know if the device keys off the length, or if it is missing the other hid messages first.

The mystery exe runs in wine and puts the icon in the panel, but doesn't send off any usb communication though.

I noticed that the last SET_REPORT differed from the previous pile of SET_REPORT

55 01 00 00   00 00 00 00

Then55 02 00 00     00 00 00 00

Switching to hid I guess.

libhidapi-hidraw0 won't open the device, and won't accept the buffer "ctypes.ArgumentError: argument 2: <type 'exceptions.TypeError'>: wrong type"

import hid

# libhidapi-hidraw0
# hid.HIDException: unable to open device
h = hid.Device(vid, pid), pid)

buf = [0]*8
buf[0] = 0x55
buf[1] = 0x01
#ctypes.ArgumentError: argument 2: <type 'exceptions.TypeError'>: wrong type
h.send_feature_report([0x55, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00])
h.send_feature_report([0x55, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00])
