I've just been handed a USB RS232 converter, which, for some strange reason, identifies itself as an HID device.
Has anyone out there ever seen one of these? If so, any ideas about linux support? I have no problem writing drivers, and it looks like we'll be using a bunch of these (if I can get them working under linux :-) We're running redhat 8, kernel 2.4.20-18 (yes, I know 2.6 has better support, but I have to deal with corporate weenies...)
Any starting point at all would be very much appreciated.
Here's what I get from lsusb:
