Description
I have:
- searched open and closed issues for duplicates
Behavior
With this script:
from escpos.printer import Usb
p = Usb(0x0483, 0x5743)
if __name__ == '__main__':
p.text("Hello, world!")
p.cut()I get this output:
Traceback (most recent call last):

return self._ep_info[endpoint_address]
~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^
KeyError: 1
During handling of the above exception, another exception occurred:

ValueError: Invalid endpoint address 0x1
Any ideas on how to fix this?
