hi...linux guys,
I have two questions about "mount -t usbfs none /proc/bus/usb":
1. what's "none" used for ? i guess that the mount source is no need here ,so just fill a "none", is it right?
2. i found there is no usbfs in Ubuntu10.04, how do i add one?

any help will be appreciated ?

Best Regards

Viktor

The explanation for any entries in fstab may be found on the man page - "man fstab". In this case the "none" indicates a subtype of filesystem. For any command you are unfamiliar with you should always check out the man page before invoking it. This includes many config files such as fstab.

There is no "usbfs" however most usb "sticks" are formatted as a FAT32 or (declared as "vfat" by fstab or "mount" options) filesystem so they are compatible with Windows and Mac.
