i work at a company with approx. 160 bloomberg users
for some reason we are having a huge problem where the bloomberg keyboards that bloomberg provides for us, keep losing power.
we were informed by bloomberg that its a driver issue, yet all the drivers that they supply for us are not working
im almost positive that this is a power issue but nobody seems to know how to fix it.
when a user is using the keyboard it will just lose power, (the LCD will shut off on the keyboard, and it becomes unusable)
when we reseat the usb cable, windows identifies its and it begins working again, but, as you can tell, this causes a huge problem as the BB keyboard is the only one attached to the users computer
any ideas? has this happened to anyone before?

Try going into control panel->system->hardware->device manager->universal serial bus controllers->usb root hub.  Right click usb root hub and select properties.  Click on the power management tab and uncheck "allow the computer to turn off this device to save power".  I suspect your problem is related to power management.  If the above doesn't help, look for other possible power management issues - maybe in the BIOS.

Is this happening to all of your 160 uses?  How often?  Does everyone use the same make/model of PC?

My first thought is that this may be related to the amount of power available on the USB bus.  Try removing other USB devices and see if the problem goes away.  A powered USB hub may be a long-term solution if this helps.

If I remember right, there is a way to plug DC power into the keyboard so that it does not rely on the USB Bus' power.  

Is that the case with your keyboards?

Aren't those the worst keybaords in the world?  If feel sorry for people who have to use them every day all day.

it doesnt seem as if there is any external power source option on the keyboards

BB sent us 10 new keyboards that they call FREEBOARDS which seem to be working, (with the exception of 1 user)

they are smaller and i believe that they prob take up less power considering thre is no LCD, and there are less keys

thanks for the help guys! ill let you know if i have any other problems with this
