i tried format adata usb stick. seemed work ok, unusual in ubuntu (and windows). in syslog, can see following output:
when run lsusb, before , after plugging in usb stick can see new device added - device 5 in list below:code:[ 125.408793] usb 1-1.2: new high speed usb device using ehci_hcd , address 5 [ 125.552498] initializing usb mass storage driver...
