Hi, I am having hard time trying to connect a device designed as save-disk for digital cameras to a FC3/FC4 machines. The device is marked USB 2.0 High Speed and carries also memory card reader (3 slots). When I connect it to the PC, I get: usb 3-2: new full speed USB device using uhci_hcd and address 8 usb 3-2: not running at top speed; connect to a high speed hub scsi10 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 8 usb-storage: waiting for device to settle before scanning Vendor: DCB Model: HS-HD Rev: 2.23 Type: Direct-Access ANSI SCSI revision: 00 SCSI device sdc: 156301488 512-byte hdwr sectors (80026 MB) sdc: assuming drive cache: write through SCSI device sdc: 156301488 512-byte hdwr sectors (80026 MB) sdc: assuming drive cache: write through sdc: sdc1 Attached scsi disk sdc at scsi10, channel 0, id 0, lun 0 Vendor: DCB Model: HS-CF Rev: 2.23 Type: Direct-Access ANSI SCSI revision: 00 Attached scsi removable disk sdd at scsi10, channel 0, id 0, lun 1 ... (similar for other memory card slots, just different lun numbers) So, it works as "full speed" only, with a rate of 1MB/s which is not acceptable for 80GB disk. At first I though the first two lines mean that the USB port used is not capable of High Speed. But then I connected to the VERY SAME port another device - memory card reader (no disk) and got: usb 1-4: new high speed USB device using ehci_hcd and address 12 scsi9 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 12 usb-storage: waiting for device to settle before scanning Vendor: SMSC Model: USB 2 HS-CF Rev: 2.16 Type: Direct-Access ANSI SCSI revision: 00 SCSI device sdc: 4001760 512-byte hdwr sectors (2049 MB) ... (other slots) ... So there are two problems: 1. Why does the device not work at 480 Mbps, 2. What do all these USB numbers mean: 1-4, 3-2? I guessed one of those should should somehow point to the USB port used but it seems it does not. No single number repeats although the cable was plugged into the same port. any ideas, explanations? regards, Michal. -- Michal Szymanski (msz at astrouw dot edu dot pl) Warsaw University Observatory, Warszawa, POLAND
