Hello. I recently got a USB hub with four ports. While I can plug a storage device, or a digital camera, into it, and read these devices separately, it seems that I cannot mount and read them at the same time (IE, view images from the digital camera, while simultaneously viewing files on the USB storage device).
Anyway, all suggestions are appreciated. Mark PS, I tried dmesg, and I don't understand what it's saying. It gives a bunch of information, and reports various errors. See an edited version of it below: usb usb1: configuration #1 chosen from 1 choice hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected usb 1-2: new full speed USB device using uhci_hcd and address 2 drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 0 pr oto 2 vid 0x03F0 pid 0x3A02 usbcore: registered new driver usblp drivers/usb/class/usblp.c: v0.13: USB Printer Device Class driver usb 1-1: new full speed USB device using uhci_hcd and address 3 usb 1-1: configuration #1 chosen from 1 choice hub 1-1:1.0: USB hub found hub 1-1:1.0: 4 ports detected usb 1-1.3: new full speed USB device using uhci_hcd and address 4 usb 1-1.3: configuration #1 chosen from 1 choice usbcore: registered new driver usbserial drivers/usb/serial/usb-serial.c: USB Serial support registered for generic usbcore: registered new driver usbserial_generic drivers/usb/serial/usb-serial.c: USB Serial Driver core drivers/usb/serial/usb-serial.c: USB Serial support registered for Handspring Vi sor / Palm OS drivers/usb/serial/usb-serial.c: USB Serial support registered for Sony Clie 3.5 drivers/usb/serial/usb-serial.c: USB Serial support registered for Sony Clie 5.0 visor 1-1.3:1.0: Handspring Visor / Palm OS converter detected usb 1-1.3: Handspring Visor / Palm OS converter now attached to ttyUSB0 usb 1-1.3: Handspring Visor / Palm OS converter now attached to ttyUSB1 usbcore: registered new driver visor drivers/usb/serial/visor.c: USB HandSpring Visor / Palm OS driver usb 1-1.3: USB disconnect, address 4 usb 1-1.2: USB disconnect, address 5 usb 1-1.1: new full speed USB device using uhci_hcd and address 6 usb 1-1.1: configuration #1 chosen from 1 choice scsi1 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 6 usb-storage: waiting for device to settle before scanning Vendor: USB 2.0 Model: Storage Device Rev: 0100 Type: Direct-Access ANSI SCSI revision: 00 usb-storage: device scan complete usb 1-1.2: new full speed USB device using uhci_hcd and address 7 usb 1-1.2: configuration #1 chosen from 1 choice scsi2 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 7 usb-storage: waiting for device to settle before scanning Vendor: HP Model: USB CAMERA Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 00 usb 1-1.2: USB disconnect, address 7 usb 1-1.3: new full speed USB device using uhci_hcd and address 8 usb 1-1.3: configuration #1 chosen from 1 choice visor 1-1.3:1.0: Handspring Visor / Palm OS converter detected usb 1-1.3: Handspring Visor / Palm OS converter now attached to ttyUSB0 usb 1-1.3: Handspring Visor / Palm OS converter now attached to ttyUSB1 usb 1-1.3: USB disconnect, address 8 visor ttyUSB0: Handspring Visor / Palm OS converter now disconnected from ttyUSB 0 visor ttyUSB1: Handspring Visor / Palm OS converter now disconnected from ttyUSB 1 visor 1-1.3:1.0: device disconnected usb 1-1.2: new full speed USB device using uhci_hcd and address 9 usb 1-1.2: configuration #1 chosen from 1 choice scsi3 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 9 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete Buffer I/O error on device sdb1, logical block 1947 attempt to access beyond end of device sdb: rw=0, want=15616, limit=15537 Buffer I/O error on device sdb1, logical block 1947 attempt to access beyond end of device usb 1-1.2: USB disconnect, address 9 FAT: invalid media value (0xb9) VFS: Can't find a valid FAT filesystem on dev sda.
