Why is it "not possible"? You want to run a kernel that has known security problems? :) > * Inside Out Networks Edgeport/1 - requires kernel version 2.4.20; > * Keyspan USA-19QW - requires kernel 2.4.18-3 modification and recompile; > * Belkin F5U103 - flat out didn't work though all indications said it should; > * IOGear G-UC232A - sometimes drops the first character it receives > (only once after app restart and only sometimes). > > The IOGear is the only one that was close to working.

The Edgeport and Keyspan devices _do_ work, if you don't insist on using a known buggy and insecure kernel that is quite a few years old... Oh yeah, there have been a _lot_ of USB fixes since that kernel release too. > [I've checked the LiNUX-USB device list.

In the mean- > time I'll keep checking items in the device list.] How about a dirt cheap pl2303 based device. That might work for your application (although I would recommend a new kernel even for that device...) Some of the older keyspan devices will work too, if you can find them around. Oh yeah, a Edgeport 2 or 4 port device (the older ones), and the ConnectTech WhiteHEAT device should also work well, along with the Digi Acceleport multiport device. But all of them are more than one port devices and a bit more expensive.
