Since one of the USB ports on m Powerbook G4 Aluminium died I'm looking for alternative file transfer options to transfer files and use a mouse at the same time.
I bought one of these PCMCIA to Compact Flash adapters but when I copy files from the CF card to the powerbook I get extremely slow file transfer rates below 1MB/s.
I can't use it during file transfer at all since the CPU usage goes up to a 100%, I can't even drag windows around.
When I plug in the same cf card to a USB 2.0 cardreader to my only working USB 2.0 port it works like a charm, I can do stuff and copy files with a breezing file transfer rate of 35MB/s at the same time.
What is the issue here?
I can recall older computers with IDE interface have these kind of issues when DMA is not enabled. But thats a Windows 9X thing.
I have no idea what to change in MacOSX to speed things up.
I'm running Tiger and Leopard.
edit: just figured that copying files from my NAS is faster than any of the local options.
still want to get the pcmcia adapter problem fixed tho.
