Hi

 

I just installed snow OSX and most is working fine. But the USB ports are not working proper. If i connect an mass storage to my laptop it does not show up. However if i add an USB mouse @ startup it works but if i disconnect it and then connect it it does not work anymore. i tryed the USB fix and there was no change.

Some good tips can be found here:

You should post specs when asking this type of question. At least the model/make of your motherboard southbridge.

http://en.wikipedia.org/wiki/Southbridge_%28computing%29

So basically what you're saying is "I have a Hewlett Packard model so and so but I'm too lazy to look up the specs for it, please do it for me".

 

Here are four ways to do it:

 

Run Lavalys Everest in Windows, make a report, examine it, make a signature with specs.

 

Use Windows Device Manager - a bit less n00b friendly though

 

On OS X you can use LSPCI: http://www.osx86.es/?p=620

 

Or, if you don't have access to the computer you need the specs for, you can use Google, starting with a model name search, then going deeper from there. But that takes time, unless you get lucky.

I could, but I'd still have to use google. You should learn how to do that yourself, it is much faster than posting on forums and waiting for someone else to do it for you. Here, let me show you how:

 

Type "PM45" (without the quotes) in the google search box. See the very first result? The one that says "Mobile Intel® PM45 Chipset - Overview"?

Good, you've hit the jackpot so click that. See the two tabs that say 'overview' and 'Technical Documents'? Click the second one.

Alright, now putting together what you learned from reading the Wikipedia page (link above in post #2), and the words "I/O Controller Hub" from the Intel website, we can quickly conclude that the Intel PM45 chipset uses the ICH9 Southbridge.

 

Follow the first link I posted and try the suggestions given in the thread.

hi,

 

i have similar problem. all of my usb ports are working with usb 1.1 speed. how can i fix it.

 

my motherboard is:

 

00:00.0 Host bridge: nVidia Corporation MCP79 Host Bridge (rev b1)

00:00.1 RAM memory: nVidia Corporation MCP79 Memory Controller (rev b1)

00:03.0 ISA bridge: nVidia Corporation MCP79 LPC Bridge (rev b2)

00:03.1 RAM memory: nVidia Corporation MCP79 Memory Controller (rev b1)

00:03.2 SMBus: nVidia Corporation MCP79 SMBus (rev b1)

00:03.3 RAM memory: nVidia Corporation MCP79 Memory Controller (rev b1)

00:03.5 Co-processor: nVidia Corporation MCP79 Co-processor (rev b1)

00:04.0 USB Controller: nVidia Corporation MCP79 OHCI USB 1.1 Controller (rev b1)

i installed snow leopard 10.6.2 and updated it to 10.6.3. everything is working fine except usb (and sound is crappy but that is not an issue now)

 

Thanks

There is no USB (EHCI) 2.0 controller present among the info you've posted. I wonder why that is.

 

It might help to use iMac10,1 for model identifier, that model has the same MCP79 chipset as your PC.

Edit /Extra/smbios.plist with all the required info. google "iMac10,1 DMI" to find the info you need. You can usually find a Linux bug report or two with all the goods.
