puntoMX Posted October 12, 2011 Share Posted October 12, 2011 Are there jumpers on that card? Sometimes you have to "tell it" to use the internal port and not one of the external ports. Link to comment Share on other sites More sharing options...
myelin Posted October 13, 2011 Share Posted October 13, 2011 I am sure that this might be the port on your casing and not on your backpanel. right? if yes than you need to attach the casing cable at the rightspot on the mobo.if not than i am clueless like you!

Ponch Posted October 13, 2011 Share Posted October 13, 2011 I am sure that this might be the port on your casing and not on your backpanel. right? ... he says the 5th port is "on the card".Could it be one of those that "features 4 external ports and 1 internal port sharing with an external port" ?

puntoMX Posted October 14, 2011 Share Posted October 14, 2011 Most cards these days are sold with a VIA chip and I think that one can be used for 4 ports, there is a NEC (D720101GJ for example) chip that can be used up to 5 ports, so we need indeed know what is written on the chip on that card...

IcemanND Posted October 15, 2011 Share Posted October 15, 2011 How about the make and model of the pci card, might help figure out the issue. Link to comment Share on other sites More sharing options...
John305 Posted October 15, 2011 Share Posted October 15, 2011 Hi as your pc is older running a large amount of usb off the mother board is not a good thing. You can buy a 7 port usb powered hub for cheap works alot better. Link to comment Share on other sites More sharing options...
b-man Posted October 21, 2011 Author Share Posted October 21, 2011 (edited) Are there jumpers on that card? Sometimes you have to "tell it" to use the internal port and not one of the external ports.no jumpers... he says the 5th port is "on the card".Could it be one of those that "features 4 external ports and 1 internal port sharing with an external port" ? i did manage to get it to work when i unplugged all the usb ports out of the back of the card so could be a sharing port... (even though nothing else on the card was currently running)so we need indeed know what is written on the chip on that cardwithout pulling it out i cant see i will have to pull it out when i have time and have a look at it and get back on thatHi as your pc is older running a large amount of usb off the mother board is not a good thing. You can buy a 7 port usb powered hub for cheap works alot better. i have an 800w psu so think it can handle it plus i dont like usb hubs powered or noti have 4 usb ports in the back on the mother board2 usb ports up front on the mother boardand this 5 port pci cardEDIT:ok so going on the shared port theory i unplugged everything at the back and it workedi then plugged something into "port 1" the back and it didnt workso moved it into "port 2" and it worksso plugged in "port 2, 3, 4" at the back and the internal port and it works so it does seem to share 1 of the portsproblem solved thanks guys especially Ponch Edited October 21, 2011 by b-man Link to comment Share on other sites More sharing options...
pointertovoid Posted October 25, 2011 Share Posted October 25, 2011 Hi as your pc is older running a large amount of usb off the mother board is not a good thing. You can buy a 7 port usb powered hub for cheap works a lot better.My opinion is the exact opposite: avoid hubs as they bring worries even if externally powered. Use only direct Usb ports.In case someone worries about the available power: a Usb 2.0 port delivers nearly nothing. Like 2.5W guaranteed maximum.

John305 Posted November 16, 2011 Share Posted November 16, 2011 Hi well to usb it makes no diffrence if you have a 1000 watt psu usb uses 5 volts. If you really want to test it plug any 16 gig usb stick into one of your front usb ports it wont work they will ony run about a 8 gig. Plugged into the back port you could run one 16 gig stick if you put in 2 you would get the Window's message everytime, the "Hub power exceeded" warning, on any connector. Using a powered hub, everything's fine as it supplys all the power to run the devices. Link to comment Share on other sites More sharing options...

Using a powered hub, everything's fine as it supplys all the power to run the devices.I thought that the USB 2.0 standard allowed for 500mA (or five 100mA "units") not that it had an 8 Gb limit.http://en.wikipedia.org/wiki/USB#PowerActually I was convinced that the power consumption needed for a USB stick was not dependant on the amount of memory inside it (if not for a trifling part) and that all sticks fell in the "low-power" category, or however well below the 500 mA limit.Which make/model are the two 16 Gb sticks that are enough to get the "Hub power exceeded" message?On which machine/motherboard does this happen?jaclaz Link to comment Share on other sites More sharing options...
Ponch Posted November 17, 2011 Share Posted November 17, 2011 I wouldn't be surprised if a 16gig today needs less power than a 128Meg from 8 years ago. And probably less than a keyboard or a mouse (which you can plug together without problem). Personally, I have NEVER seen that "Hub Power exceeded" message.

John305 Posted November 17, 2011 Share Posted November 17, 2011 Hi again this happens on a socket 775 p5q turbo asus board it has 12 usb ports. But I do remember that some manufactures ie - hp and others have said in there pc pdf information you will not beable to use all ports at once I will have a look around and find that statment.
