Upgrading from 4 to 5 USB issues

hi,

I hope someone can help me with this. I have been at it for 3 days now with no success.

I used Paralles 4 for over a year with a Windows XP Pro SP2 as a guest OS. A few days ago I purchased the upgrade to 5.

I installed parallels and when started Windows it converted the image to version 5 image. All seem to work ok EXCEPT all the USB connections. Whenever I try connect either an external usb device (e.g. flash drive) or an internal one (e.g. Apple Built-in iSight) I get a message (dialog window on the screen) that says:
"Unable to connect the USB device to your virtual machine.
The device cannot be connected now. Please try again later."

I installed and uninstalled parallels twice. I converted the old version 4 image four times with the same results (I kept an original image I keep using for the conversions). all seem to complete with no problems.

From within windows (when I start it) all devices are up with no warnings (including the USB hub device). I dont know if this is a specific driver compatibility between parallels 5 and the device on windows (?) or something else (I dont know how to check the devices on the Mac OS X.

I am at my wits end. The only alternative I see are either to revert to Parallels 4 and use the proven image.

Any ideas?

My MacBook Pro has the following:
----------------------------------
Model Name: MacBook Pro 15"
Model Identifier: MacBookPro2,2
Processor Name: Intel Core 2 Duo
Processor Speed: 2.33 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 4 MB
Memory: 4 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP22.00A5.B07
SMC Version: 1.12f5

thanks in advanced

I contacted parallels with this issue and got a few things to try. I did all they asked with no success. It's still an open ticket so I hope this issue will be resolved someday. I am pasting the reply I got from them in case it works for you or give you some ideas.

Hi, AvnerPeretz, jason hall, nimad.

To find reason of such behavior we need some additional info.
Please, do the following:

- select checkbox Parallels Desktop -> Preferences -> General -> Use detailed log messages
- reproduce the issue
- make a problem report
- post it number here
- remove back "Use detailed log messages"
 
Me too.

ID 793946.

system is Macbook 2.16 Intel Core 2 Duo w/ 3 GB RAM, OS X 10.4.11. Guest is Windows 7 RTM ~ 1.5 GB RAM allocated.

Error only occurs if trying to connect USB to Windows guest. Also if try to connect Apple Bluetooth adaptor.

I look forward to the fix.

Other than this it feels a lot more stable that version 4 and I can run in Coherence without it locking up after a time of not doing anything.

Thanks,

Duncan
 
Thanks, AvnerPeretz.
It looks like a small problem in prl_usb_connect kernel extension for mac os 10.4.x. We will fix it soon.

There is a workaround:

1. Open Info.plist file from prl_usb_connect.kext for editing in text editor. For example in vim:
sudo vim /Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.4/prl_usb_connect.kext/Contents/Info.plist

2. Delete strings which contains word PrlProbeScore (there are two of them) and save file.

3. Reboot host.

I can't seem to find the prl_usb_connect kernel extension (as mentioned above)? Can I get a bit more detail.
Click to expand...

Kernel extensions placed in the following folder
/Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.x

where x can be:
4 - for mac os x 10.4.x (tiger)
5 - for mac os x 10.5.x (leopard)
6 - for mac os x 10.6.x (snow leopard)

If you have other version than mac os x 10.4.x, please don't try this workaround - just use detailed log messages and send us problem report's id.
