Hi, I've rebuilt the latest kernel 2.5.52 and test the USB 2.0 funciton with my LaCie USB2.0/1394-Disk Drive 10GB and a Plextor PX-W2410TU USB2.0 CD-RW. It spneds about 8 minutes to copying a 300MB file. (10 times test) Do I miss some modules? Some problems I met as follows. (1)Sometimes it can copy completely in 30 seconds. Is the echi-hcd module instable or immature now? Or the VIA USB 2.0 host controller is bad support? (2) If two USB2.0 devices (HDD and CD-RW) are pluged into the same usb hub, Two situations I met as follow. ( check /proc/scsi/scsi ) A. 2 devices are found and can be attached. B. 2 devices are found but only one device can be attached. (3) What is this file, /proc/scsi/device_info, for? My configuration, KT333+VT8235+ IBM ATA66 10GB HDD. Thanks in advance. Best Regards. Joseph
