Knowing more about your use of the data, and how the data might change would help. Partitions can be marked read only or even write only. usb 3-1: configuration 1 chosen from 1 choice. This problem is actually known (ext: ELAN Touchscreen regression in recent 3.12s ), but has no known solution up to kernel 3.13.6: 3844.533281 usb 2-7: new full-speed USB device number 91 using xhcihcd 3846. via my SANE/Avision backend: usb 3-1: new full speed USB device using uhcihcd and address 2. Linux kernel: getting ELAN touchscreen to work, USB debug related. Partitions can be read or written at any offset for any span of bytes. hand when this started) I can not access some (I think all USB 1) scanners. Partitions can be used with and without formatting. I do not know about the error, but likely that if you are trying to use gadget, then this error is because it is missing a configuration step…the one turning it into mass storage.Ī question arises as to whether the nature of your data requires custom drivers, or if you could treat this like a partition (where the data partition might be VFAT or ext4 or even some custom file system type…maybe a binary unformatted partition) and simply allow the other end to look at a partition. A gadget is seen by its host as a set of configurations, each of which contains a number of interfaces which, from the gadgets perspective, are. That implies the driver at both sides will be custom.
