Ok, so I got these Durabrand 2.0 CH USB Powered Speakers for Christmas and they work great, but when I plug them into my Dell Lap Top a message pops up saying that there has been a power surge in my USB Port. I click on the message and it tells me to unplug the USB Device and reset. If I click on "Close" it says that the USB Port will no longer be functional. Is this a common problem with USB Devices? Is there a way to fix it?

I had a similar problem where I could not increase zone 2 volume - Page 100 in the manual notes that 'power amp assign' must be set to "7 Ch + 1 zone" before zone 2 max volume can be changed. Try that.
These recievers were infamous for the power transformers going bad(opening) if more than 2 speakers were hooked up and it was cranked up.Did it die while playing?Do you have 4 or more speakers hooked up?Was there a power surge?Let me know........
I recently got one of these and had the same problems. These were solved as follows.
Firstly, for small devices such as USB sticks and MP3 players they must be formated as FAT32 otherwise they cant be read, NTFS does not appear to be supported.
Secondly, for portable hard drives they must be also formated to FAT32 they also need to be externaly powered. For my 2 1/2" lap top drive the power from the USB port on the machine was not enough to fire up the drive I had to use a Y cable plugged into a mains usb charger to boost the power it then worked fine. Also be a little patient as it will take a little while to read the drive, this will depend on the drive capacity but you should hear the drive ticking over as it does this
cd players work without use of volume controls coax cables hook up's and then by setting reciever to proper button so sound can come out
you might have had a power surge that fried your system but lets look at easy stuff first
lines in properly and connected
test on an old sterio with speaker hook ups and test your speakers by plugging in to old beat box
make sure wires are not scorched
turn on receiver fm see if speakers work change channels to sterio and mono settings if speakers start to work on sterio or mono setting chances are power surge blew out your system
hope this worked
if you have a main speaker system working properly, takea known good amp to ch2. wire the main pre amp out to amp 2 input.. turn both units on(no spkrs connected), fire it up. if the amp does not go into protect mode, turn ALL power off to the system.,connect one Spkr channel on A2, AND TURN THE VOLUME DOWN FIRS!!!!. pOWER UP THE SYSTEM AND SEE WHAT YOU GET.BE GENTLE WITH VOLUME SETTINGD! If ch 1 works, repeat procedure with ch 2 pre amp out.
Based on your post/description, the Durabrand 2.0 CH USB Speaker System is a basic external speaker that plugs into your PC's speaker/headset output (green jack). It is supposed to get its power from the +5VDC supplied by the USB port. Some USB port have current limiting therefore it can be anywhere from 10 - 500 mA. The power requirement of your external Durabrand speaker maybe beyond what the PC's USB ports can supply. It does not need to be recognized by the OS since it only connects to the USB to get power but there is no data interaction.
Perhaps what you can do is get an external +5VDC power supply whose output is in USB type connector. The current rating would depend on the requirement of your speaker. Offhand, if the speakers are not that big, probably a 1 Amp would do.
This is of course assuming that the Durabrand speaker system is fully functional. If with an external power supply it is still a no go and you have verified that sound do come out of your green jack (with the use of an ordinary headset), then the Durabrand is defective.
Hope this be of help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
