VMV fails to detect K4505 on WinXP

[ljohnway]

I have installed K4505 adapter onto Acer Travelemate 8371 with WinXP SP3; VMC 9.4.4.17702. Straight after installation, 3G connection worked OK. After rebooting notebook, VMC fails to detect K4505 - 'No Device' in Mobile Connections, no adapter reported in WinXP Network Connections. Notebook also fails to shutdown.

I have uninstalled VMC, then removed the Huawei USB drivers and registry entries, and re-installed. No change.

There appears to be an interaction between Huawei USB drivers and internal Bluetooth driver (Broadcom).

Please can you advise?

A little more detail:

With VMC service disabled but K4505 inserted (slow flashing green), Device Manager reports "Vodafone Mobile Broadband-USB device (Huawei)" in Ports (COM & LPT), but no modem reported. Phone & Modem Options (Control Panel) reports "Vodafone Mobile Broadband Modem (Huawei)" - Not Present.

Hope this helps.

Hi John,

Can you try the steps listed in the attached document and let me know if this fixes the issue for you?

Jon,

Thanks for the document. Spent many hour over the weekend trying to get a working install:

a) installed fresh copy of WinXP (from Acer OEM restore CDs) onto a spare disk. Directly after Huawei/VMC installation I could get connection via VMC, but after reboot the VMC LAN driver dissappears from Device Manager, and VMC reports 'No Device'.
Tried all ways of re-installing Huawei drivers using the Wdkdi 'scripts', which reported no errors every time.

I only need RAS operation. Directly after re-installation, when VMC worked, attempting to use a RAS connection resulted in Error 777. Killing the VMC service made no difference. Is RAS supported with K4505/9.4.4.17702?

b) returned to original disk and tried Wdkdi scripts, which ran with no errors. On plugging in K4505, it fails to install all the drivers; VMC reports'no'device'. The 'CD' is not shown. It looks to me as though only ewusbfake.sys is installed.

I have attached what appear to be installation log files. If these are not correct, please let me know.

John Way

Hi John,

I'm afraid this one has me stumped, so I've escalated it to our Mobile Broadband specialist. I'll post back as soon as I hear back (but am unfortunately away until Friday).

I have run this sequence several times now with the same results:

Run WDKDI scripts to remove Huawei drivers.
Reboot PC twice.
Inserted K4505. Drivers appeard to install correctly. Finished with 'Device ready for use' message.
Executed setup_vmc_lite.exe. This appeared to install correctly, during which it appeared to re-install K4505 drivers without problems.
Device Manager reported Modem and Network devices, as well as CD ROM, etc.
Network Connections reported the LAN adapter, but no Modem.
VMC started automatically, found K4505 adapter, and network beacon. I initiated connection, but was in a building with v poor reception; no connection was made.
Probably after ~30 sec timeout, VMC abruptly dissapeared, and all Vodafone/Huawei devices dissapeared from Device Manager.
Device Manager then showed a second Fingerprint Reader with yellow exclamation icon. This was not present when installation started.

It looks as if something fatal happens at the instant when VMC closes the (attempted) connection, causing VMC to crash.

I have attached another set of logs, but cannot see any obvious problems.


Observations: Version.ini for all K4505 entries shows 'version=9.4.4.17106'. I am using 9.4.4.17702.

I only need RAS operation - is there any way of just installing the Huawei 'modem', without loading VMC, for simplicity?

Hope this helps.

Further testing done with 9.4.4.17702 R87 downloaded from Vodafone Business site seems more stable. I appear to be getting reliable RAS dialling attempts with *9***1#, web,web as we get to "Registering your computer on the network" followed by Error 619 which looks like your server rejecting my connection. Is this correct?

Questions arising:
1. What is the correct login/pwd for a contract connection?
2. Is it possible to suppress what appears to be two driver installation sessions, first on K4505 connection, second as part of VMC startup. It would seem sensible that once the correct drivers are installed, they can be left alone. Can the K4505 be suppressed e.g. with an AT string?

Would appreciate some expert assistance, please.

Looks like I currently have AT+CGDCONT=1,"IP","internet" and ATDT*99#
ie.
apn= internet
user=web
pas=web
tel=*99#

On Win98 I'm using now, it's possible to set logging from modem and connectin properties
that gives all commands exchanged. On XP I couldn't find equivalent settings and used registry
edits to set logging then turn it off before disk became full with logs. That's 12 months ago and
I forget the details. That's last time I used XP, just to grab settings needed for the connection.

VMC at that time defaulted to fixed dns ips which needed to be changed to obtain from
remote since the ips given didn't always respond. Join up for opendns if you get
desperate.

Few weeks ago I had failed connections as responses were taking something like 20 seconds
with setup of connection timed out during that period. Again vodafone claimed no work
being done but TV from same mast was on/off/on as was electric in area of mast from chorus
of burglar alarms I could hear from other side of valley.
