Sir,
Motherboard - Asus P5g41t-MLX
Last week i changed my cpu cabinet. Done the installation. But, after installation, i have some problem with the cabinet's front usb ports & audio ports.

The motherboard have 4 usb ports & 3 audio ports (rose,green.blue) at the back side. All these are working properly.
The cabinet's front panel consists of 2 usb ports & 2 audio ports (rose,green). Here is the major problem.
1) When i connect pendrives to both usb ports, they work 100%.
But
When i connect a usb modem (Huawei which i use for internet), the system detects the device, but when i try to connect to internet (Mobile Partner), the error shows as "The device has been disconnected or is unavailable".

Also, when i connect usb DVD drive, the system detects it (it shows in Device Manager & the indicator light in the dvd drive blinks). But, i can't eject the dvd drive.

2) Both audio ports not working.
I checked all these without connecting anything to the back expect a usb keyboard.

I'm feeling so bad that i cant use the front panels of a brand new cabinet. I searched alot in google & i can't get a final solution. I guess that the probelm won't be of the cabinet bcoz usb pendrives are working properly & the problem is only with usb modems & usb DVD drive. & i also done a fresh OS intall. So, it must be some other hardware problem.
I will be really greatful if someone can solve this. Waiting ...........

Sound slike you did not hook things up right to front pannel from the motherboard. Double and tripple check the manual vs what you did to make sure it's right. Are you using external power to the devices that need it? DVD and Modem is likely to need more power than a flash drive to run. Are you using a dual power USB cord? If not, try that. If you are, try using the devices that you have issues with with an external power brick.

Sir,
All connections from the front panel are attached to a single connector ( 1 connector for usb & another for audio) which makes an easy way to connect it to the motherboard. So, i don't think there is any need to refer to the manual.
I'm not using any external power to the devices. Actually, the problem is only for my cabinet. bcoz, i tried connecting the usb modem (Huawei) with another computer's front panel & it worked fine. So, the problem occurs only with my cabinet.
So, u say that dvd drive & modem need more power. So, as both worked fine with another computer, is there any problem with my smps or motherboard ?

If all you changed was the case, the issue is likely with the case connections. Try the devices with external power. You can also contact the vendor of the case and maybe the motherboard to see what they say. If your front audio does not work also, does that not give you a clue that there is something wrong with that hook up? Front USB ports dont work right, front audio does not work. If the front connections worked with your old case on the same motherboard, by elmination, it's the new case or how you hooked things up.
