Hacking ret = -1 error in usb loader

[sekhu]

|OK, so my games were crashing while running them off the HDD via usb loader. I read somewhere on GBATemp that setting the HDD to Cable Select from MAster might resolve the problem. So I did this, and when I loaded it up in USB Loader it gave the error message

Error: Could not initialise USB subsystem! (ret = -1)

Press any button to restart

So I took the HDD out of it's enclosure again, and removed the jumper from the HDD to set it back to MAster. But now when I load via USB Loader, it gives the same error message. I did reformat the drive via WBFS Manager 2.2, and the drive was recognised before, it was just games that crashed.

What can I do to resolve this? I'm on CIOS9 with USB Loader 1.1 - I was running CIOS10 + USB Loader 1.5 before previously

CIOS10 and disable the sleep feature of your HD, what make is it?

load USBloader, reinsert HDD, see if it still gives you the error.

turn off the power then connect your hdd then turn it on. thats what worked for me with that error.
