USB stick not discovered

I have a problem.
I have an USB stick that worked some time ago and was discovered with no problems.

Yesterday i installed a stripped openSUSE install created in susestudio.

The USB stick isn’t even seen when using fdisk -l.

Is there a package that the USB discovery depends on??

I even used modprobe usb-storage. And still nothing.

Help anyone.

AFAIK the ehci_hcd or uhci_hcd modules are also required.

They both are loaded.
I just checked other sure usb stick and it doesn’t work either so hardware (USB sticks) are probably fine.

I’d be interested in seeing

lsmod |grep usb

I just had a quick play with a memory stick and removing/adding those modules as well as usb_storage.

With the usb stick
usb_storage 105744 0
usbhid 52512 0
hid 41136 1 usbhid
ff_memless 8752 1 usbhid
scsi_mod 178632 6 usb_storage,st,sr_mod,sg,sd_mod,libata
usbcore 195712 6 usb_storage,ohci_hcd,usbhid,ehci_hcd,uhci_hcd

Without the usb stick is the same.

What about dmesg |tail output after device plugged in?

Looks like it is being discovered. But it isn’t seen by the partitioner or it isn’t mounted at all. fdisk still doesn’t see it

I resolved it by restarting the PC with the stick inside. Now it is being discovered normally. Now i wonder why it didn’t work earlier? Thank You for Your help.
