I was wondering if someone would be willing to write or port (from Linux) a driver for external USB hardrive using the InSystem ISD200 cable.
It doesn't work with the regular umass driver.
It seems that it is a bulk/bulk/bulk transport protocol device, but using an alternative encapsulation of the ATAPI protocol on top of that.
Here is the Linux driver listing:|src/|src/drivers|src/drivers/usb|src/drivers/usb/storage
I'm unfortunately not a developer but I would be pleased to help...
External harddrives like "Memup 60Go 5400rpm USB" need this driver to work.
