Hi,
I have come in several occassions where when i install the USB network adapter cards into the computer whether into a win98 machine or 2000 or linux machine ,the machine freezes and i have to remove that and only it will reboot again .But i'm pretty sure that the card is working fine since it works fine with other computers .
I have installed the USB ports properly and the other USB devices work fine with the same computer.
I have seen these issues in many computers and in some cases it will say fatal error occured and will reboot itself saying that memory dump error has occured and it will say dumping memory like that
Even in Linux machine it seems to install properly but when we reboot it will not allow to reboot .This is not the case with a particualar product or a manufacturer but this occurs only with the USB network cards like USB ethernet adapters ,USB ADSL modems etc .

I know there is exactly some known issue over this ,but unable to get the info on this issue .
Iwant you to help me since my profession involves in installing these cards
Any help will be greatly appreciated

I suppose you use the latest drivers of your network card. Try to install the drivers first and then to plug in the usb network card. Try also to remove any other usb device, connected to the same usb controler and leave the network card only.

I have already using the latest drivers for the USB anyhow thanks for your answer .I have already indicated that this card works with the same drivers in another computer

If this is a USB device connected to the USB ports on the PC, try using a powered USB hub.
You may be exceeding the available 5 Volt power on the USB port, and that is locking up the PC.

If this is a plug-in card, check for IRQ conflicts.

Many motherboards assign default IRQs to the motherboard slots. Some slots share IRQs with system resources, or other slots.
If the board demands an IRQ different than the one assigned to the slot, you may get a conflict that stops the PC from booting.

The simple approach is to try the card in another slot.

I have checked the IRQ conflicts ,but in many cases it is not allowing any thing to access nor the mouse or the keybooard works,the only way to get into the computer is to remove the card
Thanks for your answer
