Hi Linus,

I've performed some checks by using a USB monitor program - which allows trial runs for free.
Unfortunately this shows nothing happening at all from the PC end when using
the bootloader USB mode.

As a comparison, if I boot Rockbox first, the logged data starts with the
000001: Get Status Request (DOWN), 07.04.2006 12:59:41.2451792 +142.9856032
Get status from Device. Data length 0x2 bytes (00 00)
000002: Control Transfer (UP), 07.04.2006 12:59:41.2451792 +0.0
Pipe Handle: 0x85a0a9f4
  03 00 ..
Setup Packet
 80 00 00 00 00 00 02 00.......
 Recipient: Device
 Request Type: Standard
 Direction: Device->Host
 Request: 0x0 (GET_STATUS)
 Value: 0x0
 Index: 0x0
 Length: 0x2
(This then succeeds every time.)

I've now tried this on 2 other PCs - both running Windows XP SP2 - and all 3
machines give exactly the same results. In the unlikely case it's relevant,
my Iriver firmware is 1.28E, and (duh) I am using the USB 2.0 Device port
(not the USB 1.1 Host).

Any other ideas for ways in which us users could help..?
