View Full Version : USB problem or ?
08-17-2004, 11:18 AM
At the firefly setup the usb will not detect receicer. I have win2k os. I have K7s5a pro mother board. I check it out on another computer running xp and the remote and reciever work. Anybody have any ideas. Any help would be appreciated.

when it is plugged into the win2k computer does the red light on the receiver light up?
if not the port isnt getting any power.
If it does check the device manager for an unknown device, if you plugged it in before windows installed the driver it will not re-detect it again.

The red light is on (on the reciever) and the remote light is on. It will load the driver in device manager. If i reboot the computer with the receiver plugged into the usb, the install progam will show the usb connection. It then jumps to the (Push the OK button on the remote) screen. If i push the button on the remote the red light flashs on the remote. The receivers light is on. At this point nothing happens.

Here's what I did:
Close the firefly setup
unplug the receiver
plug in the receiver
windows xp will incorrectly detect the receiver (triple beep sound for failure)
go to the device manager, and notice the question marked item
right click on it, and uninstall the device
unplug the reciever
now, run the setup again
when prompted, plug in the receiver
it should detect it at this point
Basically, it seems that once you've plugged in the receiver before running the setup, windows installs some non working driver, which resides there even if you unplug it. In order to uninstall it, it has to be plugged in.
Product Support, give this a test - it worked for my system, and i see no information anywhere on this situation, besides saying that it will no longer work if you plugged in the receiver before running the setup (which obviously is of no help). Many people naturally plug in USB devices before running a setup program, as they are considered plug and play.

Here is what i would do...
Uninstall the Firefly software and driver, unhook the receiver from the computer, restart the computer.
Now you are starting with a clean slate.
Install the firefly software.
when the setup program tells you too, plug in the receiver.
follow the steps and everything should be good.

i have the same issue, devices gets recognised as "unknown device" because i plugged it in before installing the drivers.
i tried uninstalling the "unknown device" from the "universal serial bus controollers" section of the device manager while it's plugged.
i after that uninstalled and reinstalled the drivers from the cd, but the installation program nevers gets to recognize that i plugged it in when it ask me so. (the unknown device shows back in the device manager).
anyone knows how to make it work?

go into safe mode menu by pressing F8 while starting up the computer(after initial checks)
you may have to employ the press-release technique (press the button then release. repeat until the menu shows.)
use arrow keys to select safe mode then press enter
go into device manager and all devices will show. uninstall all unknown devices then restart
install the firefly software
then plug in the reciever when prompted
all should be fine then.

do you have an x10 / ati remote installed as well?

I occasionally find myself in a situation where the receiver does not show up on boot up. I think I may have traed it to a "loose" fitting USB plug on the receiver end. If I slightly pull the reciever out of the USB outlet on the machine it usually works.

i just redid a clean install of windows to try to fix this problem.
same issue, when the installation program ask me to plug the receiver, nothing gets detected and a new "unknown device" gets installaed in the device manager.
i tried installing the same receiver on 2 other pc without any problem.
on those pc, when i'm asked to plug in the receiver, i get the familiar "du ding" sound that says the usb device is plugged before the setup program continues with the installation (by asking me to press the ok button on the receiver).
i'm not getting this sound on the faulty pc with the fresh windows install (and my sound drivers are working)
my motherboard is an Asus p5vdc-mx rev1 with lastest bios drivers.
i installed the lastest via motherboard drivers and windows updates on the pc before trying to install the firefly receiver.
this sounds like the usb would have a problem on this pc but i have a usb keyboard, mouse and media reader (cf/sd flash card reader) plugged on this pc via usb and they are all working correctly.
i'm lost, anybody has any clues on what i should try next?

i was finally able to make the receiver on the faulty pc.
i installed a new usb pci controller and plugged the receiver in one of the usb port of the new card. it worked instantly!
i also noticed that the red light on the receiver was not as bright when plugged on the faulty usb ports.
could it be that the voltage is not high enough on the built in ports?
can someone tell me what are the power requirements of the receiver so that i can measure what the motherboard sends and know if the problem comes from there?
i'm still intrigued to know what the problem is on the build in ports, this might be usefull to someone else in the future...

I have exactly the same problem. I have 2 pc that are not working with it, while 3 others works. I freshly installed one of the PC and everything is the same. It's not the problem of plug in before software installation. Because the ones that work always recognize it as "RF Receiver Device" while the bad ones always see it as "unknown device"
It's not the issue of power either. I put it in a self-powered usb hub and it still doesn't work. To me, it's most likely the issue of USB mis-communication(TM by Bush). It doesn't matter it's USB 1.1 or 2.0 either. The 2 pc that are not working, one uses nForce2 usb2 chipset while other uses sis usb1 chipset.
All I can say is that firefly is really a picky one, just like my ex-girlfriend, too bad I still want to live with it.
