A lo mejor aqui esta la solucion como mucha gente en el mundo se queja de este error:
There seems to be a lot of buzz around (check google) with this RAS error, that USB stick and Toshiba laptops in particular. Someone on a Romanian forum has suggested that Toshiba's install of XP is somewhat unique and lots of people have been chatting about ways to fix the fault - although no two seem to have the same answer! This suggests other factors at work also.
Have a read through the conversation on this Romanian forum (its translated by Google so the language is a bit quaint) - you may be able to try some of the ideas out to see if any work for you
Another clue is that the USB stick has an area of flash memory that emulates a CD for you to install the VMC software from. Sometimes this can block the modem from being accessed - VMC has to switch the "Zero CD" off to allow the 3G modem to be accessed. Perhaps for some reason it is not working on the Toshiaba? So you could try the following to see if it helps (I'm not 100% sure that this command will work with your specific modem, but it works with other Huawei 3G sticks)
QUOTETo stop the USB stick from starting as a CDROM you send it the initialisation string AT+ZCDRUN=8 You can do this with Hyperterminal in Windows XP but not in Vista which has no Hyperterminal. There is an alternative way that does not need Hyperterminal: in the Windows computer with the USB stick inserted go to Start/Control Panel/ Phone&Modem Options/Modems/ZTE proprietary modem/Properties/Advanced. Place in Extra initialisation string AT+ZCDRUN=8. Then connect using the Telstra Turbo Connection Manager. Remove the MF626 Delete the string in control panel. You can reverse this process by repeating the procedure usingAT+ZCDRUN=9.
You may need to customise the above to locate your specific device in .../Phone&Modem Options/Modems/ It should be relatively obvious from the specific modem you have there..
Sorry I can't help more - I don't have that particular modem, but ran into similar issues trying to get another Huawei stick working in a Linux environment. It was the ZeroCD that was causing all the grief.
