Do you have the USB drivers compiled in or as modules? I know some years |
| 15 |
ago, in some cases they'd only work as modules. This was with USB 1.1 |
| 16 |
hardware, but maybe USB 2.0 has similar issues? |
| 17 |
|
| 18 |
Anyway, since then I've always compiled them as modules, and haven't had |
| 19 |
a problem, other than once when I booted my backup installation which was |
| 20 |
outdated and didn't have modules for the current kernel, and I ended up |
| 21 |
without keyboard and mouse since those are USB. Fortunately I have the |
| 22 |
ACPI power switch detection setup to shut-down, so I was able to do so |
| 23 |
gracefully and reboot to a different kernel, but it was certainly |
| 24 |
frustrating, as I prefer to compile in all the basics. I've been going |
| 25 |
to test a newer kernel with the drivers compiled in, but so far haven't |
| 26 |
gotten the appropriate round tuit... =:^( |
