I have problems to get access to my
usb 1-1.2: Product: TSE USB stick
it is recocniced as
usb-storage 1-1.2:1.0: USB Mass Storage device detected
For windows there is a driver so it's possible to connect to it on COM3.
Using the usual connect code it's not possible to write/read to the device.
import usb.core
import usb.util
dev=usb.core.find(idVendor=0x04b8, idProduct=0x0638)
print(dev)
if dev.is_kernel_driver_active(0x0):
try:
dev.detach_kernel_driver(0x0)
except usb.core.USBError as e:
sys.exit("Could not detatch kernel driver from interface({0}): {1}".format(i, str(e)))
dev.set_configuration()
msg = '<open_device><device_id>local_TSE</device_id><data><type>type_storage</type></data></open_device>\0\0'
print(msg)
print(dev.write(0x1, msg))
ret = dev.read(0x81, 512, 100000)
This results in:

How is it possible to force linux to reconize the nano-USB-stick on /dev/ttyUSB* and not as mass-storage?

So there are some GET messages. And after the 3 Set messages it's possible the device is changed so it's possible to read/write.
