I got a new USB 3.0 4-port card in the mail today.
You bought in online? What is the URL of the page advertising the product that you bought? That should presumably provide some info regarding what this device is?
New 4 Port USB 3.0 Hub PCI-E Express Card Adapter 5Gbps For Windows 2000 XP Vista Win 7 - Newegg.com
I installed the card and Windows could not find the driver for it. It came with a CD which has drivers for every product they make so I don't know which one to install.
Is it from Transcend? StarTech?
Many vendors use electronics from Renesas, so the drivers are for Renesas.
Of course there were no instructions and it came from, right China and I don't see a product brand on the box.
What are the names of the folders/files on the CD that supposedly has the correct driver for your particular card?
See Below
If you go into Device Manager (right-click on Computer, select Properties, then select Device Manager) you should show some unknown device as "other", probably with yellow exclamation mark on it or something like that.
Right-click on the unknown item, select Properties, then select Details tab. It might show something in the value details for the first item (device description) in the Property dropdown list. Does it? Something like Renesas USB 3.0 controller?
See Below == It is not Unknown. No Yellow Mark. I clicked on the "Update Driver" below but Windows could not find one and also I installed Renesas but that didn't work either. == I also install the "NEC 3.0" from the CD, but no help there.
If you select the second item (Hardware ID's) in the Property dropdown list for your unknown card you will hopefully see a series of values. These define the manufacturer and hardware device codes, which correspond to the required driver. Can you please post a screenshot of the values shown here.
Finally, are the supposed driver installers on the CD in "EXE" form, or are they folders which somewhere in a sub-folder they contain an "INF" file? The EXE driver installers might be unpacked/extracted by running them (if they are self-installing), and the imbedded folders could then be examined to look for a README or INF file (which provides detailed driver info).
There are many different ones, appears to be for different products.
If they are already expanded driver installation folders (which contain INF files), you could try getting Windows to do all of the searching for you. Again, right-click on the unknown item in Device Manager, and select "update driver software.... Then from the resulting dialog window asking "how to search", select "browse my computer for driver software", navigate to the CD, be sure the "check sub-folders" item is checked, and OK. Hopefully Windows will drill down through all sub-folders on the CD, and will hopefully find the matching INF file to correspond to that Hardware ID I asked for earlier, and then perform the correct driver install automatically.
I was not able to get Windows to search the CD. == There were a couple Help files, but they were written in broken English and not much help. This is the last time I buy a "no-name" product from China. Luckily it was only $11 so not a big loss.
Report back.
