Packet Size 0 So I have 3 USB devices they are USB Version 1.0, USB Version 1.16, and USB Version 2.0 compliant. The Cypress Semiconductor 120GB Hard Drive is USB Version 2.0 compliant, it is connected to USB Version 1.0 Hub. This limits the speed to 12 Mbit/s. If hub was USB Version 2.0 compliant the speed would be up to 480 Mbit/s. They all work but HD is slow and Device: sdb = 120 GB Cypress Semiconductor USB 2.0 External Hard Drive Problems: Sometimes mounts to /mnt/removable sometimes to /mnt/memory_card one time to /mnt/removable2 Other Drives & Storage: ImageMate CompactFlash USB Problems: Sometimes mounts to /mnt/removable sometimes to /mnt/memory_card It seams to work best if Ext. HD is off and memory_card is in reader, I boot then turn on HD. If HD is on and memory card is not in reader I boot, them HD mounts to /mnt/memory_card, Other combonations are unpredictable. Question can I install some software to make Hub USB Version 2.0 compliant? If not Is there hardware to install? How can I get these devices to mount in same place every time. -- Ray Hogaboom
