My USB stick (256MB Memorex) is randomly mounting or not when I plug it in and also when I restart. I never know when it is going to show up or not. I have tried formatting it as FAT and also as HFS. Same result either way. Running Leopard and I get the same result in 10.5.1 and also now 10.5.2. Oh, and it never recognizes it in the keyboard, only if I plug into the back or into my USB hub. If I take this exact stick to work and plug it into a Tiger OS iMac, all is well. Anybody else have this issue?
