|As I have said, if you can't get the front ports to work properly with all USB devices that work in the back ports despite them being connected to the header correctly, you have to change the wires to them, or use one of the alternatives I mentioned. |
I have one cheap generic case that has such inadequate front port wiring, and I have encountered other cases that have that problem.
e.g. if you can get at where the wires are soldered on despite the ports module being riveted on and you have or can borrow a soldering iron, buy a short USB 2.0 rated cable, chop the connectors off of it, and use that cable.
Or drill out the rivets then you should be able to change the wires - fasten it again with rivets or sheet metal screws of a suitable size.
USB 2.0 rated cables merely have wires that have specific wire gauge or larger and they often also have a braided wire shield around them in the cable (it connects to the port's ground). An unrated cable MAY work, it may not.
- for a friend's computer case she needed ports higher up on the front of the desktop (tower) case, because she uses a power wheelchair and USB cables or devices plugged into the ports lower down can be damaged by her wheelchair footrest platform hitting them.
I got her a cheap card reader device that installs in a floppy bay on the front of the case (or it can be installed in an additional adapter for installing a floppy drive in a 5 1/4" bay) that also has two USB ports with the proper wiring (to connect them to the pins on a header for two ports that has the same connections as yours (on an Asus mboard) . Since it's an older card reader (it may not recognize a card larger than 2gb) I got it locally for a clearance price - $6 - from a small place that builds custom computers and has lots of computer parts.
The model of the mboard is helpful, but it would also be helpful if you supplied the Aspire model number. Someone might have replaced the orginal mboard - if so, the front port wiring/female connector(s) for it may not have the same use for the 5th connection in one row, and if so, you might get the message
"Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port."
regarding the front ports.
There are 4 GA-8PE667 models
I chose the plain GA-8PE667 model.
English manual download connection from America poor for me. I chose Europe.
9 pins on a double row 10 position header
Note the 5th connection for USB overcurrent on the 5 pin side of the header, and that the 4 pin side has no 5th connection.
The 4 pin side probably uses all odd numbers starting at 1
The pin in the 5 pin row beside 1 is 2, the other pins are probably 4,6,8,10
+5v (usually pin 2), D-, D+, Ground, Overcurrent
+5v (pin 1), D-, D+, Ground, No connection and probably no pin
That is the same pattern as some other mboard manufacturers use, e.g. Asus, and is common pattern for generic 2 port USB wiring adapter's female connector(s), etc., and SOME case front 2 port wiring.
- if the wiring has individual connectors on each wire, or individual connectors for +5v and ground, a dual connector for data, it will work with this header and all other (or many others if it has dual connectors for data) , but if there is a 5th wire for one or both ports, it may or may not be compatible with what the header intended for it to be connected to - don't connect it if in doubt.
- If the female wiring connector is one piece double row, one pin hole blocked in a corner, it will work and can only be installed on the header one way, if the use for the 5th connection for the header and the port are the same - if they're not the same, you must either cut the 5th wire or release it's metal end from it's socket in the connector.
- if the wiring has two female connectors for a pair of ports, one 4 in a row (always has 4 wires) , the other 5 in a row, 5 wires (some have 4 wires - not applicable in the following)
- the wire for +5v , often red or a solid color other than black, should be on pins 1 or 2 (the one in the other row beside 1 in any case) in this header.
- if the use of the 5th connection in the one row is the same for both the header and the port (it can be either overcurrent, or a second ground for the outer metal "shell" of the port), the 5 in a row connector can be on the 5 pin side without you getting an error message from the mboard, or the 4 pin side (no connection to the 5th wire) ; the 4 in a row connector can be on the 4 pin side, or the 5 pin side (no connection to the 5th pin).
- if the use of the 5th connection in the one row is NOT the same for both the header and the port, the 5 in a row connector CANNOT be on the 5 pin side without you getting an error message from the mboard - you must place the 5 in a row connector on the 4 pin side (the 5th wire has no connection) ; the 4 in a row connector goes on the 5 pin side (no connection to the 5th pin).
- if the wiring has two female connectors for a pair of ports, both 5 in a row, 5 wires.
- the wire for +5v , often red or a solid color other than black, should be on pins 1 or 2 (the one in the other row beside 1) in this header.
- if the use of the 5th connection in the one row is the same for both the header and the port, you can connect either connector to either row.
- if the use of the 5th connection in the one row is NOT the same for both the header and the port, the 5 in a row connector CANNOT be on the 5 pin side without you getting an error message from the mboard - you must place one 5 in a row connector on the 4 pin side; the other 5 in a row connector goes on the 5 pin side, but you must either cut the 5th wire or release it's metal end from it's socket in the connector.
Also in the manual....
Bios Setup - Integrated Peripherals
- USB Controller - Enable (or Disabled) (so you have one controller) - must be enabled if you want to use the onboard USB, of course.
- USB Keyboard Support - Disabled (or Enable)
- USB Mouse Support - Disabled (or Enable)
You only need to enable these if you want to be able to use a USB keyboard to access the bios Setup, or if you want to be able to use a USB mouse in the bios Setup.
In many bioses there is no support for using a mouse of any kind in the bios Setup.
In most bioses, if you're not using a PS/2 mouse, disabling support for a PS/2 mouse in the bios frees up IRQ 12 for use by other devices (sometimes disabling it doesn't allow any device to use IRQ 12) - but you have to make sure the PnP config has it set to PnP use in the bios. Not many things can use IRQ 12, but some network cards and USB controllers can.
The USB headers for a particular mboard manufacturer are identical for models made about the same time, but sometimes a manufacturer changes that over time.
That applies in the case of Gigabyte mboards.
Older Gigabyte mboard USB headers (oddball)
10 position double row header.
+5v, D-, D+, no connection and no pin, Ground
Ground, no connection and no pin, D+, D-, +5v
The proper one piece double row female connector for the 2 port plate has blocked holes where there is no pin on the header. It can't be placed on the header backwards - it can go on either way.
I have one - it's not compatible with any other manufacturer's USB header - you're unlikely to find one locally.
Obviously 4 in a row connectors will not work with the older headers. Commonly wired 5 in a row, 5 wire connectors will work if you pay attention to which wire connects to the +5v end in each row, but only if the use for the 5th connection for the 5 connection side is a second ground.
Another oddball header.
This was used on older Mitac mboards - e.g. many older Compaq models made ~ 1998 to 2001 or so have OEM only Mitac mboards.
10 position double row header.
Ground (pin 1), Dat 1+, +5v, Dat 2+, ground
Ground (pin 6, beside pin 1), Dat1-, +5v, Dat 2-, no connection and no pin.
Commonly wired 4 in a row and 5 in a row and commonly wired one piece double row connectors cannot be used with this header. You can use double connectors for DAT 1 + and - , and and Dat 2 + and -, across the rows.
