logitech dinovo laser desktop - reciever problem

[pmp2]

Hi!

I tried to ask logitech support but they didn't even understood my problems, so maybe some of advanced users here will help me:

I got two logitech desktops which utilizes as a reciver small "Logitech Bluetooth 2.0 EDR" unit. Everything was working okay, as long as "SetPoint (which is a software for keyb/mouse) management" found and update and updated itself to a some newer version (i was using 2.44C from CD) - probably 2.47.

At one PC upgrade process went okay, but there's a serious problem on second one. While upgrading process computer hanged up, and now:

1) after i plug logitech usb reciever into USB it's detected as "broadcom bluetooth download device"
2) i got no driver for this device
3) i got no proper .dfu file (working reciever is reported as "Logitech Mini-BT reciever"" and no idea how can i download it from working one ?

NOT working is detected in device manager as:
USB\VID_046D&PID_C70F\5&2F6F8AF0&0&1

Working ONE is:
USB\VID_046D&PID_C709\000761416744

Reciever is based on broadcom chip - BCM 2045. widcomm software which were bundled on CD was 5.0.1.801 and it report working reciever as:

Vendor: Broadcom Corporation
F/W version: Version 2.1.58.0

Device addres: MAC 00.07 etc
HCI version: Bluetooth HCI 2.0
HCI release: 2000
LMP version: Bluetooth LMP 2.0
LMP subversion: 413A

if i understood correctly posts on this forum - i could fix my problem by uploading to broken device proper .DFU file, or i'm wrong and should i send "dinovo desktop" for RMA (i do not wanna do it - christmas time, and probably i will get replacement after new year :()

I'll be very happy if someone could help me, please.
regards,

Hi pmp2,

i have the same problem on my Desktop PC, the update failed.

i put the stick in my laptop but at the same time i press the Button on it, then i install the Driver CD and the online update to 2.47 than its work again.

My EDR stick have the Firmware 2.1.71.0

PS: I make a update again on my laptop with the stick now the firmware is 2.1.85.0 (SetPoint 2.47.864)

You mean that your reciever was also detected as "Broadcom Bluetooth Download Device" due to SetPoint installation hang-up ?

If so - what happened after You pressed red button while pluggin it into USB ? I tried it, and it's still detected as "Broadcom Bluetooth Download Device".

I tried to install SetPoint 2.44C from CD on a fresh windows installation, but installation program want me to plug compatible bluetooth device :( (it does not detected reciever in DFU mode)

And last question, what do you mean by running online update ? How did you do that ?
