Hi,
currently I'm trying to load my mp3-player (Philips HDD 100B) on an virtual windows xp. I use that mp3-player as data storage under linux for a while now but to integrate mp3s in the database of the player you need the software which comes with it (win32 only). However, when try to load it in VMware I get this error:
| Quote: | | The specified device appears to be claimed by another driver (usb-storage) on the host operating system which means that the device may be in use. VMware Workstation cannot safely take control of the device until the host driver is unloaded. |
...so I took the following steps:
-> recompiled the kernel with usb_storage as modul
-> added usb_storage to the blacklist (/etc/hotplug/blacklist)
-> unload it (modprobe -r usb_storage)
The weird thing is that I still get the same error in VMware. It seems that the usb_storage modul is still loaded but even an 'lsmod' doesn't show it.
Then I tried to remove the modul with 'rmmod'...
| Code: | # rmmod usb_storage
ERROR: Module usb_storage does not exist in /proc/modules |
ehm... 
I can still mount the mp3-player under linux so the usb_storage modul must be active but... where is it and how can I kill it?
some infos:
-> /etc/fstab
| Code: | | /dev/sda1 /mnt/usb auto noauto,user,rw 0 0 |
-> lsusb
| Code: | | Bus 001 Device 008: ID 0471:014a Philips |
-> dmesg
| Code: | usb 1-2: new high speed USB device using ehci_hcd and address 9

Let's hunt and kill it!

If it's not a module, but it still works, then it's likely built-in. When you rebuilt the kernel to build usb-storage as a module, are you sure you copied the new kernel image correctly (and with a mounted /boot...) ? That command will tell you the status of usb-storage option in the running kernel (ie compiled as module or built-in or disabled):
| Code: | | zcat /proc/config.gz | grep USB_STORAGE |

That's it, thx widan!
| Code: | | CONFIG_USB_STORAGE=y |
I copied the new kernel image correctly but I don't know that I have to reboot the kernel (I seriously thought running 'modules-update' would be enough  )... sry to have bothered you!  |
