GPIB-USB 82357B clone/Info

This is the lsusb output on a Linux system.

Note that endpoint 2 IN has a max packet size of 511, which is not entirely compiant with the USB standard. When enumerating, the Linux kernel warns about this:

config 1 interface 0 altsetting 0 bulk endpoint 0x82 has invalid maxpacket 511
