I spent today working on a bug in the driver for the TI UIF MSP430 programmer. It stopped initialising properly in 2.6.24, but it worked in 2.6.23. I did a git-bisect between those versions to find the commit that induced the fault. I narrowed the search a bit by telling git-bisect to work on commits only in drivers/usb/, as I hypothesized that the bug was induced somewhere in there.
About 10 builds and 20 reboots later, I found the commit in which the problem was happening, and then read some stuff about USB etc (the LWN device drivers book proved invaluable yet again) and subsequently generated a patch. I’ve sent it to (what I think are) the right places.
If you can’t wait for the next kernel release (if it passes review…), then you can rebuild the ti_usb_3410_5052 module by downloading this tarball, untarring it and then running “make” in the resulting directory, and then “make install” as root. You will need enough of your kernel’s sources hanging around to do this. In Fedora, these are provided in the kernel-devel package.
Update (5th April ’08): The patch has made its way into Linus’s tree, so I think it’ll be in 2.6.25.
