Happy to find /dev/uba

When I compiled my 2.6.9 kernel, I intentionally eliminated some SCSI support after realizing that my CD drive could now be handled as an IDE device. But I lost -- or thought I had lost -- support for my USB hard drive.

When I've wanted to back up my files to that drive, I've been rebooting into kernel 2.4.26, which provided SCSI support for my external USB drive.

Today I realized that 2.6.9 has been apparently been recognizing my external USB drive all along. I ran across three devices, /dev/uba, /dev/uba1 and /dev/uba2, that I hadn't known were there. I fdisked /dev/uba, and there was my external USB drive sitting there waiting for me. I would have used something like "/dev/usbhda" rather than "/dev/uba", but a rose is a rose ...

My question: What is creating this device for me? I couldn't find anything in my udev rules mentioning a device named "ub*" or any such thing.

Check dmesg for mentions of it.

dmesg |grep -i usb
dmesg |grep uba
