Has anyone gotten the ubsa driver to work correctly with a Belkin F5U103 USB to RS232 adapter? I was running 4.7-RELEASE and needed support for this device. I tried two things: 1) I first tried upgrading to 5.0-RELEASE and compiling the kernel with: device ubsa device ucom During bootup, I always saw the following messages and /dev/ucom0 was not present after boot: ====== uhci0: <VIA 83C572 USB controller> port 0xd400-0xd41f irq 5 at device 17.2 on pci0 usb0: <VIA 83C572 USB controller> on uhci0 usb0: USB revision 1.0 uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered ubsa0: Belkin Components F5U103 Serial adapter, rev 1.10/2.04, addr 2 ubsa0: failed to set configuration: SHORT_XFER device_probe_and_attach: ubsa0 attach returned 6 uhub0: port 1, set config at addr 2 failed uhub0: device problem, disabling port 1 ====== 2) Thinking that 5.0 might be a bit too leading edge for me, I wiped it out and installed 4.8-RELEASE, which also has ubsa support. Again put the same kernel config changes in and this time the dmesg output looks fine; all I see is this: ubsa0: Belkin Components F5U103 Serial adapter, rev 1.10/2.04, addr 2 and after MAKEDEV'ing /dev/ucom0, I can actually open it. HOWEVER, nothing seems to happen. When doing "cu -l /dev/ucom0", I'm not able to communicate with any serial devices. The lights on the Belkin indicate that at first, it is receiving characters during my "cu" session (the green LED blinks) but after a while, even that stops happening... ------- USB keyboard and mouse work okay. And I've tried two different Belkin adapters, both of which work under Windows, so I don't think it's a hardware or BIOS configuration problem... Any help would be GREATLY appreciated! I desperately need to add a couple more serial ports to my machine, and USB is really the only free port I have. Thanks, Steve Lin
