USB flash drive driver missing
I have a SanDisk Cruzer Titanium 1GB USB flash drive that has suddenly stopped working on my Windows XP Home Machine. The device worked perfectly for about three months when suddenly--totally out of the blue--WIndows has started classifying it as an unknown device with no driver installed. SanDIsk claims the driver is native WIndows XP, but I can delete it by editing the Windows registry. Even if I was satisfied with this solution--I'm not; it seems like unnecessary brute force--the specified entries to delete are not present in registry!
Any ideas why my flash drive went wonky? And better yet, how do I fix it?
