Problem with docking station

---

I brought the 1st party docking station for the P500 (the SDT-140), and am having problems with it.

When I plug the phone via the dock into my powered hub, Windows complains that 'This USB device is not recognized'. Plugging directly into my computer, Windows recognizes the device, but tells me that 'This device can perform faster', and when copying files to the SD card, maxes out at ~1MB/s (compared to the 5-6MB/s i can get when copying to a USB pen drive). I have tried using a different cable, and different ports, but still have this problem, any ideas?

(P500 running stock firmware, V10b-DEC-13-2010, Android 2.2.1, kernel 2.6.32.9)

A possible fix

As this happened to me (but with other USB devices, not the phone) I can only suggest you this fix. Please note that you may temporarily lose control of your input devices (mouse and keyboard) if they are connected via USB.
- unplug all of your USB devices (except for the mouse and keyboard)
- open the Device Manager and uninstall all of your USB Host Controllers. They may have a longer name, such as "Intel ICH10 Family USB Enhanced Host Controller - 3A3A" or whatever. This will also remove the corresponding USB root Hub.
- if you have a PS/2 keyboard, you will still have some control over the Device Manager window and will be able to continue without rebooting your computer. Using the keyboard's arrows, select the computer name at the top of devices' list. Press the "Menu" key (it's placed at the bottom right, between right Alt and right Ctrl and has a list select symbol on it). This is the equivalent of right-clicking with your mouse. Press down arrow to select the only option - "Scan for hardware changes" and hit Enter. This will detect and reinstall all of your USB controller drivers and re-activate all the USB ports.
- if you have an USB keyboard and it stops responding (because you just unistalled its USB controller) simply power off your PC using the power button and then turn it back on. The drivers will be reinstalled during the boot.

I hope this solves your issue with the low transfer speed, or maybe even the "This USB device is not recognized" problem. There's no risk involved with this procedure so just go ahead. Good luck!
