>Description:
This device seems to work fine umct0: Belkin USB PDA Adapter Belkin Components, rev 1.10/1.02, addr 2

but the DB-25 umct1: USB-RS232 Interface Converter USB Ver1.1 Device, rev 1.10/1.02, addr 3 adapter fails with the endpoint timeout when I try to open the port in minicom at 2400 n81.

minicom: cannot open /dev/ttyU1: Input/output error

>How-To-Repeat:
connect the following usb to serial adapter and try to use it in minicom.

 port 2 addr 3: full speed, power 100 mA, config 1, USB Ver1.1 Device(0x0230), USB-RS232 Interface Converter(0x0711), rev 1.02

>Fix:
Not known. I will say that while this adapter works on Linux and Windows, if I unplug it while the port is in use, it blue screens windows XP and kernel panics Linux. NetBSD is the first operating system I've plugged a USB to serial adapter into, opened the port and removed the device and it hasn't paniced. Excellent work.
