USB Device Not Recognised on Bootloader

hdubli said:

This is based on my experience with two UNis..one Exec and other JASJAR..both had same problem...this is how I solved :

-Put yr device in bootloader Mode
-Disable USB in Active Sync
-Now connect woth USB cable and open mtty utility
-Select the "WESUSB... " port
-You shall see a blank white screen..press Enter to get "USB>"
-Then type ( as BUzz has informed) set 14 0
(here I wud like to inform that after doing the above I did not get success so I typed set 14 10,then set 14 9 for two three times)
-Then I ran the ROM Upgrade directly(After enbabling the USB)
-I then followed the procedure as informed on the COngratulations Screen that is hold the two "-" buttons and soft reset and then pressed 0
-I got them back to normal..


I hope this helps to all my friends...Pls feel free..pls do not trouble our Buzz..he might be busy in inventing something more to our devices

I have a problem. My Exec is stuck on the bootloader screen. All I see is Serial at the top, and v1.00 at the bottom.

When I connect my exec via USB, the screen continues to say Serial (rather than switching to USB) and the PC I connect to 'installs' the device as 'unknown device' in device manager.

I've seen mention of the problem elsewhere on the site, but the only solution I can find seems to be to keep trying, and eventually it's recognised. So far, after three days of trying, it has not been recognised.

I am aware of Buzz tool to get the device out of bootloader mode, but that required a connection to be established, which at the moment, I can't do.

Has anyone got any experience of this, or any ideas as to what's causing this, or how this can be fixed? I have tried uninstalling the 'unknown device' from device manger, restarting the PC (and hard reset of the Exec) then reconnecting, but the same thing happens every time.

Just noticed your user name, I was a big Amiga fan a few years back, still fire up Amiga forever occasionally on my PC when I feel the need.

Any ideas would be appreciated, as I'm currently staring at a rather expensive paper weight.

Thanks Niketkumar - unfortunately it's the step before your suggestion kicks in thats the problem - the device won't connect to the PC, so when using mtty WESUSB..... isn't an option, only COM1 and COM2.

Shuflie, I've tried with three separate USB cables on a laptop and desktop (neither through a hub, and the same device has worked fine on both laptop and desktop before).

I fear a trip to the doctors is in order ...

Very frustrating because the PC sees a device, but installs it as unknown device. Anyone know if theres a Windows CE device driver that I could try and install as an overide (i.e. in device manager on the PC go to update driver and browse to a WinCE.inf or equivalent?)

Failing this, has anyone got any clue what needs to be fixed? Or how much it might cost?
