Today I re-installed my old PC for my sister. First obstacle? I obviously had changed the boot order to put the CD Rom Drive after the harddrive, making booting from my Windows install DVD hard, to say the least. I couldn’t change it because, for some reason, the BIOS refused to recognize my USB keyboard. And unfortunately I seem to have no more PS/2 keyboards.
After a bit of trial and error, it seems that only one of the USB ports on the rear is recognized during POST. And on the Asus P5QD Turbo mainboard it’s the port directly next to the on board NIC port:
So if you have this issue with any Asus board, try that USB port first. Of course if you have a PS/2 keyboard handy, that’ll do the trick as well.
For a while now I’ve had the issue that, sometimes, my iPhone would not be recognized by iTunes and wouldn’t sync. Sometimes there was an error message; sometimes not. Most recently, I would just get the Windows’ sound you get when you connect a USB device twice in a row. The iPhone then charged, but did not sync at all.
Last night it got to the point where it just simply did not work at all anymore, so I had to look into it. Much to my surprise, the relevant article on the Apple Support Site, iOS: “Device not recognized in iTunes for Windows”, actually helped. In my case, I had to remove and reinstall the Apple Mobile Device USB driver.
Reinstall the Apple Mobile Device Driver
- Right-click the Apple Mobile Device entry in Device Manager and choose Uninstall from the shortcut menu.
- When prompted, select the box “Delete the driver software for this device” and click OK.
- In the resulting dialog box, click OK.
- In the Device Manager window, right-click Universal Serial Bus controllers and choose Scan for hardware changes from the shortcut menu.
At this point, the Apple Mobile Device entry did not reappear. Checking in the “Computer” window – the one which has your drives listed – showed an “Apple iPhone” device. I found it in the Device Manager under “Portable Devices”. I had to then update the software:
- Right-click the Apple iPhone, Apple iPad, or Apple iPod entry in Device Manager and choose Update Driver from the shortcut menu.
- Click “Browse my computer for driver software.”
- Click “Let me pick from a list of device drivers on my computer.”
- Click the Have Disk button. (If the Have Disk option is not present, choose a device category such as Mobile Phone or Storage Device if listed, and click next. The Have Disk button should then appear.)
- In the “Install from Disk” dialog, click the Browse button.
- Use this window to navigate to the following folder: C:Program FilesCommon FilesAppleMobile Device SupportDrivers.
- Double-click the “usbaapl” file. (This file will be called “usbaapl64” if you have a 64-bit version of Windows. If you don’t see “usbaapl64” here, or if there is no Drivers folder, look in C:Program Files (x86)Common FilesAppleMobile Device SupportDrivers. instead).
- Click OK in the “Install from Disk” dialog.
- Click Next and finish the driver-installation steps. Open iTunes to verify that the device is recognized properly.
This worked – as soon as I clicked “next”, the iPhone’s screen lit up and it started synchronizing.
This was on Windows 7 64bit, do check the article for other versions and more detailed descriptions.
