I have a wierd issue going on. I bought a Sandisk Cruzer mini this weekend. When I connecct it to my 12" Powerbook, it will not read at all. However when I connect it to the usb port on my usb keyboard, it will read. The keyboard is apple hardware btw. How is it that it can read throught the keyboard, but not directly on the laptop?

I just bought this thing too for my PowerBook G4/500. It worked after a reboot, but I put it to sleep, wake it up, then when I insert it the light goes out and the system log reports:
Mar 7 18:27:26 localhost kernel: USBF: 593.322 AppleUSBOHCI[0x1194000]::MakeDevice error setting address. err=0xe00002ed device=0x141dc00 - releasing device
The SanDisk box for the Mini Cruzer says that OS X is supported.
Any help?

Reformatting the device did the trick!

I had a similar problem. My Lexar USB flashdisk would work fine on my PC, fine on my G5's front port, but not apparently on my blue & white G3 via the keyboard ports.
Reformatting (as FAT32 on the PC) didn't help.
Moving the keyboard to the other USB port on the back of the machine (from "USB1" to "USB2") did the trick. Now works via the keyboard USB ports. Can't explain it, but there you are.

you know, I noticed the same thing. the key works great on the port closest to me on my powerback, but not the one behind it at all.

Well, things are not so easy for me now.
I reported that reformatting fixed the issue. However, after a few iterations of going to a PC, copying data, and going back to the PowerBook, it stopped mounting the device again. Light flashes a couple of times, no mount, no message in the console, USB Prober shows no USB devices attached. Moved it back over to my iMac, mounts just fine. So, something about certain PowerBooks are an issue. I reformatted it on the iMac again, and it mounted on the PowerBook again no problem.
So, something is corrupting something on the Cruzer so that the PowerBook won't mount it. The iMac (running same OS) seems to not have any issue. What's weird is that the Cruzer doesn't even show up in the USB devices. I would expect that the PB would at least *see* it if it can't mount it.
I'm going to experiment further to see if the PC is doing something. I'll try to restrict data between the iMac and PB to see if it flakes out again. If so, I'll restrict it to a MacOS format only.
I hate being an Apple OS product tester. I don't even get paid for it.

Even with the 10.3.3. update (which has new USB extensions), the USB drive is still flaky. If I copy a file onto it from a PC, it will often not mount on the PowerBook. Sometimes, it will mount after unplugging/plugging 3-4 times. If I mount it an reformat, it's very reliable.
It seems to read more reliably on my 17" iMac than the PowerBook
I suspect that Apple's USB drivers for these devices are not well debugged.
