Question about Micro Innovations Compaq CPQ24USB
I;m having trouble trying to find which ac adapter to use for this hub ! can anyone tell me the specs for the ac adapter Please cant find any help from manufacter >
First, it should be noted that the CPQ24USB is bus powered (does NOT require AC adapter in most cases) and will support multiple (up to 4) devices that are NOT solely bus powered or or draw very little current such as: optical mice transceivers, printers, and thumb drives.
If, however, you intend to use multiple power hungry devices that are solely bus powered and draw higher current values than a single USB port on your PC or Laptop can typically handle, you WILL NEED and A/C adapter that is unfortunately no longer made by MicroInnovations (Compaq).....
WORKAROUND: Purchase, borrow, or hunt down & dig out that old multipurpose generic AC/DC selectable (changeable) power adapter with variable voltage and a variety of different sized male adapters. IT IS IMPORTANT TO LOOK AT THE SPECIFICATIONS!
Make sure it supplies the following OUTPUT:
Voltage: +5.0 VDC (not AC!)
Current: .2 - 2.5 Amp (do not exceed this current rating)
Polarity: Tip = (+) positive ' Ring/Sleeve = (-) negative
(it is very important that you observe correct polarity so check the switch on power adapter to make certain the INSIDE of the male plug is the POSITIVE DC OUTPUT, and that ground is on the outer metal sleeve)
This is based on US voltage standard so input would of course be 120 VAC and max current of 5A, but there are travel adapters for foreign countries that would supply these output requirements while accepting the DIFFERENT VOLTAGE standards of other countries if required.

Remember the help below is only a fix for seeing the error message not for overdrawing the port.
To stop overdrawing the port you need to either use a power supply or a double USB cable.
To prevent seeing the USB Power Surge alert message, complete the following steps:
Click on START, Click on CONTROL PANEL, Double-click on the SYSTEM icon, Click on the HARDWARE tab, Click the DEVICE MANAGER button, Click the "+" next to Universal Serial Bus Controllers to expand the selection.,Right-click and select PROPERTIES on the Intel® USB UNIVERSAL HOST CONTROLLER (not the USB Root Hub),Click the ADVANCED Tab, Check the box that says: "Don't tell me about USB errors"
