Satellite Pro M70: removal of the USB device causes other peripheral USB does not work

Withdrawal/use of a USB for a USB device causes devices on USB port to get affected.

Satellite Pro M70-199 (2 GB RAM)
Windows XP Pro (SP2) with all updates of Windows installed until end of October 2006.
This laptop has 3 USB ports.
An Eicon Diva ISDN USB modem is connected to a USB port.

When certain devices connected to a different USB port are deleted (even if removed safely with "eject" or "remove device safely", it causes the ISDN modem to file either a double channel (64 k + 64 k) ISDN, or for the ISDM modem to disconnect completely.)

Cause this include any memory stick USB, MP3 player (ipod and creative zen) and so on.

Do other devices, such as USB external hard drives & sometimes external DVD USB drives, and sonetimes do not produce this problem.

Is this a known issue?
If it is a hardware interrupt problem, how to solve it?
This problem is related to the modem and the laptop?

As a note, in addition, intermittent (random) times (cannot reproduce all the time, but it happens once or twice a day) when a USB device is accessible it causes the modem USB ISDN to drop a single channel, even if the lights on the modem still show it as it is connected. In this case and the case above, the only way to get the modem ISDN USB running again is physically disconnect and reconnect.

The reason why it is a crucial issue is that:
(1) the modem speed is halved or disconnected
(2) the ISP continues to full rate for a double load connection even if a channel has been dropped.

Any help will be greatly appreciated.

Here is some information on USB devices, followed by some information about IRQ settings.

Hello

I have Satellite M70-159 and I didn t notice any strange problems with the USB ports. I use a few of them as printer, webcam, USB, memory stick, optical mouse, and external HARD drive. The devices are recognized correctly and I always remove without option delete without danger.

Now I have Vista pre-installed and there is no problem so far. If I understand you right USB ports work fine but there is problem with USB modem only. Am I wrong?
Also try to contact the producer of modem support. Is perhaps the question like this known and if all goes well, they have a logical explanation.
