AssertionError: Header not accepted on PS2268

I'm trying to run this on an ASUS Transformer T100TA which has an embedded 8Gb flash drive with the Windows recovery partition on it. I'm now running Ubuntu on this device and would like to rewrite this flash, but it appears to be read-only. Is there any software controllable read-only flag on this device?

Mode: Firmware

I have tried reflashing the firmware (in firmware and boot modes) but I get the following error:

The flashing actually appears to have worked, as it was originally showing version 01.00.10, but the drive itself still seems to be read-only (even if I use hdparm -r 0 and remount the drive).

no sg or sr

Hi,
I'm on manjaro, and I can't find any sg or sr devices in /dev/.
Is there a new way to access the mid-level SCSI layer?
my usb is /dev/sde.

OSError: [Errno 22] Invalid argument

I'm trying to use this on an ASUS Transformer T100TA, which I'm lead to believe has a Phison USB controller with an 8gb flash drive, originally used for the recovery partition. I'm running Ubuntu on it now. It's definitely available (read-only) on /dev/sda

    ret = fcntl.ioctl(self.device_handle, SG_IO, args)

Does this mean it's the wrong kind of controller, or do I need to use a different device?

list_devices fails with

libusb is not set up or installed properly.

Even though it (and the dev headers) are installed ok. Does it need 'setup'?
