Environment:
EM250 Netbook (basically an Acer)
Windows 7 Starter
4GB Sansa Clip+
Versiion V01.02.15A
Basically is the device will not attach in MTP mode. Works fine in MSC, but MTP is required because the device was bought specifically for use with audible.com audiobooks, and that does not work in MSC mode.
Got the “This device cannot start. (Code 10)” bye looking inproperties after driver fails to load. Two “insertion event” bleeps are heard during the process
Tried the " Net localgroup Administrators local service /add" from http://kb.sandisk.com/app/answers/detail/a_id/192
The command was successful, but did not fix the problem.
Tried updating every driver I could find. Ran the sansa updater to make sure that everything was up to date.
The device fails the same way on an Acer netbook, and similarly on a WinXP desktop.
Watching the instal in the control panel’s device manager, you can see the low level driver load and the portable device become active, but then the MTP user level driver fails.
from the event viewer I see the following events associated with the insertion
Event ID 24576 Information: “Drivers were successfully installed for device USB\VID_0781&PID_74D0&REV_::8<.”
Event ID 25089 Information: “It was not possible to access the device () after installing drivers. Error code 0x80070651.”
Event ID 10110 Critical: “A problem has occurred with one or more user-mode drivers and the hosting process has been terminated. This may temporarily interrupt your ability to access the devices.”
Event ID 10111 Critical: “The device MTP USB Device (location Port_#0003.Hub_#0005) is offline due to a user-mode driver crash. Windows will attempt to restart the device 5 more times. Please contact the device manufacturer for more information about this problem.”
I suspect the key error is the “Error code 0x80070651.”, but I have not found a solution for it online that works
