Hi all, I've been trying to work around problems with my Maxtor external USB drive (can also use firewire). The problems is that it mounts just fine and works for a brief period of time (not sure that it uses USB2 driver on my machine though) and in the middle of copying files it stops working and tells me that it cannot copy files. Invalid Block device and i cannot unmount it. Only solution that i've found is a reboot ! and then it works for a couple of minutes again. When i look at /var/log/messages it tells me that: last message repeated 15 times Mar 7 23:50:37 localhost modprobe: modprobe: Can't locate module block-major-68 Mar 7 23:50:37 localhost last message repeated 15 times Mar 7 23:50:37 localhost modprobe: modprobe: Can't locate module block-major-69 Mar 7 23:50:38 localhost last message repeated 15 times Then it continues this error for about 10 more times. lsusb -v tells me (amongst other things that) Bus 004 Device 001: ID 0000:0000 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 9 Hub bDeviceSubClass 0 bDeviceProtocol 1 bMaxPacketSize0 8 idVendor 0x0000 idProduct 0x0000 bcdDevice 2.04 iManufacturer 3 Linux 2.4.22-1.2174.nptl ehci_hcd iProduct 2 Intel Corp. 82801DB USB2 iSerial 1 00:1d.7 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 25 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x40 Self Powered MaxPower 0mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 9 Hub bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type none wMaxPacketSize 2 bInterval 12 Language IDs: (length=4) 0000 (null)((null)) Bus 003 Device 001: ID 0000:0000 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 9 Hub bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x0000 idProduct 0x0000 bcdDevice 0.00 iManufacturer 0 iProduct 2 USB UHCI Root Hub iSerial 1 3c00 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 25 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x40 Self Powered MaxPower 0mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 9 Hub bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type none wMaxPacketSize 8 bInterval 255 Language IDs: (length=4) 0000 (null)((null)) Have anyone seen anything similar ?? I've encountered this issue with all kernel for Fedora core 1 that i've tried. When booting knoppix and trying to copy files it just works ?? Any help will be greatly appreciated, Thanks in advance Lasse Christiansen
