This is driving me nuts, and I apologize if this has been covered before. I've searched the archives & WiKi as well as Google, but apparently I'm still overlooking something. The answer will probably be something pathetically obvious, but I need to get this working ASAP.

Just compiled a new kernel (2.6.15.6) in Slackware 10.2+, and I can't get my USB flash drives to work. Other USB devices work, including the keyboard & mouse. Flash drives worked fine in my previous 2.6.11.7 kernel.

Here's the /var/log/messages output:

With the same kernel, this is what I get at home with the same flash drive:

What am I missing in the kernel???? I don't seem to be getting a /dev/sda device created.

Thanks!

Did you add SCSI disk support to the kernel, or as a module?

BLK_DEV_SD and USB_STORAGE are compiled in.

with the new kernel (2.6.15+), you must have a new version of udev. i have also recently upgraded my kernel to 2.6.15.6 and my udev to 087 (current version 088) and everything is working fine. Flash drives / external hdisk are detected and proper dev names created. please read the following page and you should have no problems afterwards. make sure you upgrade the other packages included in the site also.

Thanks, I'll look into that.
