May I force the O.S. to scan all USB devices?


Kernel 3.2.29, Slackware 14.0

Hi: the USB device is in the development stage. It has already been recognized by the system: lsusb prints vendor and product IDs. Now, it has begun to fail. lsusb does not show it. Does it even make sense the phrase "to force the O.S. to scan all USB devices"? If it does, how do I do it? lsusb merely looks into /proc/bus/usb directory.

I doubt it would because when you plug in an USB device the kernel will notice it. If USB fails during development then enabling all available related kernel modules debug switches would make sense?..

It would certainly do. But it was a silly intermittent connection in the device hardware. It seems now to perform well. 'lsusb -v' extracts a wealth of information from the device (in reality the information was extracted at device insertion time).

Now, Windows has the "Add new hardware" service, which scans all hardware physically installed in the machine. I thought Linux had something of the same sort. Isn't an inspection of all external buses done when installing the O.S.?
