Data Abort exceptions on Windows Mobile platform with USB based NIC and ActiveSync

i'm working on USB to ethernet device on both WinCE and Windows Mobile 6.5 platforms.

I have connected the USB based NIC to my windows CE craddle which has WinCE 5.0 installed on it.I don't have any problem using this NIC on WinCE5.0.

But when i connected the same NIC in the craddle which has got WIndows Mobile 6.5 installed on it i got this data abort problems! whenever i try to plg/unplug ActiveSync cable some couple开发者_如何学Go of times to the pc i'm getting the "Data Abort" error frequently.some times the error could be "Prefetch abort" and "Undefined instruction" also!

I could realize that the ActiveSync and the NIC use RNDIS functions. I saw some of these messages when i debug the problem!

NDIS!ndisMWakeUpDpcX() line 1089 + 8 bytes NDIS!CeKeDpcQueueThread() line 67 + 24 bytes COREDLL!ThreadBaseFunc() line 633 + 8 bytes

Can anybody help with you inputs? Any kind of suggestion is appreciable.

• Thanks in advance.

It sounds like your OEM's NDIS driver (or ethernet driver, or USB driver, etc...) implementation has an issue. You should contact their support line and ask for an update.
