Lion + Parallels 6 unable to connect USB

Done, Report ID: 9620762

Incidentally, the same happens with a fresh WinXP VM installed from scratch. Also happens if I install Paragon NTFS 9 and reinstall PD6 (not that I thought that would make a difference, but I noticed MacFuse wasn't installed like it is on my Snow Leopard machine, so I figured I'd install NTFS drivers just in case).

After upgrading to Lion, external USB blu-ray drive no longer mounts in Windows 7 Ultimate (64).
I tried rolling back to an earlier snapshot, no luck.
 
Here's my experience

Specs: iMac late 2009 model, lion and Parallels 6, latest build, VM = Windows 7, the 300 GB drive is docked in a Thermaltake BlacX Duet external Storage controller- Serial ATA-300- 300 MBps.

When I plug in the USB cable from the storage controller I get a apple prompt that says "The disk you inserted was not readable by this computer", option are Initialize, Ignore, Eject. Once and a while I'll get the Lion OS prompt to link the device to Lion or the Windows 7 VM.

Technically Parallels 6 didn't give me an error but I went ahead and gen'd a problem report - 9622970

Perhaps my problem is not being caused by Parallels 6.
 
VictorV, your problem isn't related to Parallels; in you case OS X itself isn't reading your drive. You may have a drive or dock problem, but I don't see how it's a parallels issue -- certainly not the same as this thread. Good luck!
 
The drive is encrypted with Windows 7 BitLocker encryption so I"m not surprised Lion can't initialize it. I thought I could bypass Lion and simply have W7 initialize the drive. Like it was before I upgraded to Lion. If others are able to mount their USB devices to Lion and just not their VMs then perhaps my problem is Lion specific...

However, I have a separate external Seagate 2T Hard Drive (not using the Blacx Duet USB Storage Controller) with a split partition, one for TimeMachine and the other for Windows 7 and that has no problems being seen by both Lion and my W7 VM.

Perhaps the storage controller is not compatible with Lion + P6... Probably not the case...

Thanks for the feedback DoniK. I'll keep looking for a solution.
 
Hi guys, after having updated my MacBook Pro with Lion I had the same problems with the not connecting USB devices to Parallels 6. I solved the problem with reinstalling the 12094-Parallels-Update a second time. Then I reinstalled the Parallels Tools out of the Parallels menu bar with /virtuell machine/ parallels tools install new. And I didn't uninstall any Software before the reinstalling. Now it works perfect again...

Interesting that a reinstall works for some, not for others. Hopefully root cause analysis by Parallels support will help determine why.
 
Thank you for reports, we do appreciate it. We're now investigating the issue.
 
Same Issue

I have the same issue. Have just upgraded from Win XP to Windows 7 on my iMac and Parallels 6. The only reason I am running Parallels is to run Quicken in the Windows environment and because i do not now have even a network connection (or access to any other USB items) I am stuck. I have tried the fix outlined in the following thread:

http://kb.parallels.com/6913

by using the following line in terminal mode to no avail:


sudo sed -i".bak" '/PrlProbeScore/d' /Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.4/prl_usb_connect.kext/Contents/Info.plist

I fear I am not smart enough to execute the script outlined in the above post. I just don't know how to do it and I would be willing to try if anyone could walk me through it. But, of course, I would rather have a permanent fix.

Please help!
Thanks,
Fred
 
hi, here is what helps me:
1)run VM
2)Connect USB
3)Sellect connect USB to VM, after that will appear "Unable to connect the USB device to your virtual machine." but...
4)restart windows (USB is still in!)
5)after restart windows see USB
 
EUREKA -- A PERSISTENT FIX!!!

So remember when I said I'm also seeing the same USB mounting problem with VMware Fusion & 10.7? Well, VMware support figured it out!

This worked for me for both Parallels & VMware: http://communities.vmware.com/message/1807841#1807841

NOTE: PaulMcg's life-saving workaround [thanks again!] is temporary; this should be permanent.

Solution

I can confirm PaulMcg's solution works instantly.

Just open a terminal window and paste the following:

sudo kextutil -t /Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/
 
Yes, but you have to run that after each time you boot your VM. The suggested fix in my post above is persistent.
 
Permanent solution that worked for me

I have a MBP 15" 2010 with OS Lion and Parallels Desktop 6 build 12094. I was having a similar problem: when I plugged USB flash drive Parallels asked if I wanted to connect it to Lion os VM; I chose VM and the drive was "ejected" from Lion but was not connected at Windows (an error message said it was not possible to start the USB device).

After trying unsuccessfully reinstall the driver for USB flash I reinstalled Parallel Tools (this option is available at "Virtual Machine" menu) and now the problem is completely solved.
 
Confirmed, USB Drive now working

Like the last user, I just reinstalled Tools and now my W7 VM can see the external USB connected, windows encrypted hard drive.

I thought I did this awhile back and it didn't work but now it does. I also should note that I installed the latest Lion update.

Thx

I'm running the latest Parallels 6 build, and just upgraded to OS X Lion, Win 7 VM. Also having the issue with USB drives.
I came across this article http://go-dslr.com/reviews/mac-os-x-lion-what-works-and-what-does-not-photography-and-others
And ran the following command, while the VM was running:
pauls-imac:~ paul$ sudo kextutil -t /Library/Parallels/Parallels\ Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/
Password:
Warnings:
The booter does not recognize symbolic links; confirm these files/directories aren't needed for startup:
/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/Contents/CodeDirectory
/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/Contents/CodeRequirements
/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/Contents/CodeResources
/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext/Contents/CodeSignature

Suddenly, magically, I am able to attach the USB drives to the VM.
I didn't have a problem with anything else, so I just ran the USB related fix.

I'm confident that this could be in the next update, its a pain to have to do it every time I start a VM manually.

Thanks for this - that same sudo fixed an issue with an R/C flight sim (Real Flight) not recognizing the installed USB controller!

BTW - installed Parallels 7 this morning and it appears to resolve this issue.
 
so we have to pay yet another $49 to keep getting bugfixes? ... seems like just yesterday I had to pay to upgrade to Parallels 6 and now I have to pay upgrade to 7 already if I want it to keep working like it did before Lion :(
