with kernel kernel-2.6.8-gentoo-r7 my usb iomega superdvd burner was working fine, but after upgrading to 2.6.9-gentoo-r1 i just get this output from dmesg and no devices: PCI: Enabling device 0000:0d:00.0 (0000 -> 0002) ACPI: PCI interrupt 0000:0d:00.0[A] -> GSI 10 (level, low) -> IRQ 10 ohci_hcd 0000:0d:00.0: NEC Corporation USB PCI: Setting latency timer of device 0000:0d:00.0 to 64 ohci_hcd 0000:0d:00.0: irq 10, pci mem e188e000 ohci_hcd 0000:0d:00.0: new USB bus registered, assigned bus number 2 hub 2-0:1.0: USB hub found hub 2-0:1.0: 3 ports detected PCI: Enabling device 0000:0d:00.1 (0000 -> 0002) ACPI: PCI interrupt 0000:0d:00.1[B] -> GSI 10 (level, low) -> IRQ 10 ohci_hcd 0000:0d:00.1: NEC Corporation USB (#2) PCI: Setting latency timer of device 0000:0d:00.1 to 64 ohci_hcd 0000:0d:00.1: irq 10, pci mem e1890000 ohci_hcd 0000:0d:00.1: new USB bus registered, assigned bus number 3 hub 3-0:1.0: USB hub found hub 3-0:1.0: 2 ports detected PCI: Enabling device 0000:0d:00.2 (0000 -> 0002) ACPI: PCI interrupt 0000:0d:00.2[C] -> GSI 10 (level, low) -> IRQ 10 ehci_hcd 0000:0d:00.2: NEC Corporation USB 2.0 ehci_hcd 0000:0d:00.2: irq 10, pci mem e1892000 ehci_hcd 0000:0d:00.2: new USB bus registered, assigned bus number 4 ehci_hcd 0000:0d:00.2: USB 2.0 enabled, EHCI 0.95, driver 2004-May-10 hub 4-0:1.0: USB hub found hub 4-0:1.0: 5 ports detected usb 4-2: new high speed USB device using address 2 ub: sizeof ub_scsi_cmd 60 ub_dev 924 uba: resid 18 len 0 act 0 uba: device 2 capacity nsec 50 bsize 512 uba: tag orig 0x3 reply 0x2 uba: made changed uba: tag orig 0x4 reply 0x3 uba: device 2 capacity nsec 50 bsize 512 uba: tag orig 0x5 reply 0x4 uba: device 2 capacity nsec 50 bsize 512 /dev/ub/a:end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 unable to read partition table /dev/ub/a:end_request: I/O error, dev uba, sector 2 Buffer I/O error on device uba, logical block 1 end_request: I/O error, dev uba, sector 4 Buffer I/O error on device uba, logical block 2 end_request: I/O error, dev uba, sector 6 Buffer I/O error on device uba, logical block 3 end_request: I/O error, dev uba, sector 0 Buffer I/O error on device uba, logical block 0 unable to read partition table usbcore: registered new driver ub both kernels have the same configuration. if it's useful to test with a vanilla 2.6.9 kernel, please let me know...
yes a vanilla kernel test would be hand. Thankyou
it turns out that i'd accidentally enabled the Low Performance USB Block driver (BLK_DEV_UB) while doing "make oldconfig", and that was exactly the cause of troubles. disabling it gave me back my burner functionality...
Can you please close this?
i've changed it to invalid... hope it's right...
