I�m new to Mac and have just got my PB17 (Rev. D) for a month.
I have experienced very very strange USB 2.0 card reader problems with my Powerbook.
I have a generic brand USB 2.0 8-in-1 card reader, which I have used for 1.5 years with my PC. The reader is perfectly ok on my PC. However, the same card reader would occasionally �hang� during transfer when connected to the Powerbook. The problem is not card-related because it occurs on all my SD/CF/MS-Pro.
After put up with it for two weeks, I bought a new SanDisk ImageMate 12-in-1 USB 2.0 cardreader which is certified for Mac. Well, the �hang during transfer� problem disappeared! But�. another strange new problem surfaces � the SD card volume becomes �Read-only� in Finder. I can no longer copy any file onto my SD card with my Powerbook! But using the same SanDisk card reader and the same SD card on PC, everything becomes normal (no more readonly). And to be even more weird, the SD card volume returns to normal if I plug the SD Card in my old generic card reader and connect it to the Powerbook. What the hell is going on!
Sorry for a long message and my lousy English, to sum up in short:
Card reader A: Generic 2.0 8-in-1
Card reader B: SanDisk ImageMate 12-in-1 Mac certified
Reader-A and Reader-B both work normally with Dell notebook.
Reader-A + SD/CF/MS-Pro would �hang during transfer� occasionally.
Reader-B + SD would becomes a �Read-only� volume (as shown in Finder and Disk Utility)
Reader-A + same SD the volume would return to �Read-Write� again
