I recently bought a fujifilm finepix 1300. Cool stuff and works with minimal effort with USB.
However, after a few days, I was not able tomount the usb mass storage of the cam anymore. It reposted at mount :
mount: /dev/sdb1 is not a valid block device
checked the process table and saw several usb processes in Z state. I killed their paret and that went away. still usb-storage was loaded. Tried to remove it -- oops process in D state. Note that khubd also was in a Z state. All was not recoverable so a restart was needed.
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 8 0.0 0.0 0 0 ? Z Nov16 0:00 [khubd <defunct>] root 18297 0.0 0.0 1568 496 ? D 11:13 0:00 rmmod usb-storage
when going singel user I saw :
pci_pool_destroy 00:07.2/uhci_desc e851ec000 busy d5d4c0000 busy
also in the logs stuff :
kernel: usbdevfs: USBDEVFS_CONTROL failed dev 29 rqt 128 rq 6 len 4 ret -6 kernel: usb-uhci.c: ENXIO 80001d80, flags 0, urb c94880c0, burb c9488dc0 kernel: scsi3 : SCSI emulation for USB Mass Storage devices kernel: Vendor: Fujifilm Model: FinePix 1400Zoom Rev: 1000 kernel: Type: Direct-Access ANSI SCSI revision: 02 kernel: Attached scsi removable disk sdc at scsi3, channel 0, id 0, lun 0 kernel: usb-uhci.c: ENXIO 80001d80, flags 0, urb c9488dc0, burb c94880c0 last message repeated 2 times kernel: SCSI device sdc: 16000 512-byte hdwr sectors (8 MB) kernel: sdc: Write Protect is off kernel: sdc: sdc1
note that the initial sdb1 now all over sudden was changed into sdc1.
