Windows 7, iPhone and DELL USB Chpiset

I found out an issue on two DELL computers, I wanted to post it here if anybody else comes across the same isse. Hope this is ok with you guys.

iPhone is a Dominant Design though Started to test Windows 7 and discovered that the iPhone and iTunes got a problem with it. Windows 7 wants to install the iPhone as MTP USB Device, which fails. iTunes want's to access the iPhone (responds with Error 0xE8000065) and starts to freeze. Unfortunately the Windows Media Player 12.0.1700.0 freezes as well.

I guess Apples Service and the MTP Protocol from Windows are fighting against? The MTP USB Device is always being tried to be installed by Windows 7, with no luck. Somebody has a solution for this?

--- Solution ---
Finally fixed it. I don't trust DELL internal USB HUB's.

I guess what happens is the following, the chipset of the DELL USB Hubs seems to add nonsense characters to the iPhone DeviceID (VID_05AC&PID_1292) in my case it added a 2nd Device plus "&MI_00" (VID_05AC&PID_1292&MI_00). Resulting in two devices being "connected". While this might be OK - I'm not a HW Person - it lead to Windows 7 believe the second is a standard MTP Device. Whilst the DeviceID has not been used for the second, I guess it run's over the deviclass (Class_06&SubClass_01&Prot_01).

So it's trying to install it twice and as a 2nd MTP Device which then results in the protocol clash & timeouts between Apple USB Driver and Windows trying to speak over MTP.

In short:

• Bought a VIA PCI USB 2.0 Host Adapter (Via Chipset)
• Plugged my iPhone into it
• Enjoy my music and other features.

anybody else had this issue? I'm on a DELL XPS420, had this with XP, Vista AND Windows 7. Until I got the PCI Hub..

sounds like alot of fun!
actually no but wow.. Dell needs to do something about their computers. If they can't connect to iPhones there will be alot of unhappy customers. Not everyone is good with computers, half the population would probably hire someone to fix it.

yes, I think so. When I search through the internet it's a very remote issue. I guess there are maybe 1-2 series of DELL which used a certain chipset.

However, I'm not in the position to verify it...so let's give it to collective intelligence

So I had a similar issue. My system (Dell m6400) also wanted to install my iPhone as MTP USB Device. In Device Manager, I uninstalled this and then clicked install driver. I selected the option to automatically download driver from Windows Update.

That worked. Everything is working fine now.

FYI... I have two Dells, an optiplex GX270 and a latitude D610. Both running windows 7 32 bit RTM, both work fine with the iphone, itunes and ipod. I did install itunes before connected either device.
