 |
|
Alrighty, here's my problem.
On my most recent install of Gentoo I'm having issues with my USB DVD-RW drive. It was accessible as /dev/sr0 during the installation process. In my new system, its detected but no device node is made. The /dev/cdrom symlink points to my ide cdrom drive, /dev/hdc.
I figure this is just a horribly misconfigured kernel but I'm somewhat new to this stuff and after screwing with the SCSI options for a while I'm stumped. Any help would be greatly appreciated.

| Did you add SCSI CD-ROM (CONFIG_BLK_DEV_SR) support to your kernel? |

| Yes, along with every other kernel option I thought might help (which granted I probably don't know what I'm doing, but still). |

Had the same problem with my USB DVD-CDROM drive.
CONFIG_BLK_DEV_SR helped for mounting data but I couldn't rip audio CDs.
Adding CONFIG_CHR_DEV_SG,
| Code: | make && make modules_install
modprobe sg
|
did the trick. 
Cheers, |
