i dont know the answer
If you are getting an IRQ conflict after installing a new HW/SW you can see whats wrong by seeing IRQ settings of all the installed devices in the machine. To view your current IRQ (Interrupt Request) assignments in a Windows XP machine you can open Device Manager. Click on Start, click on Control Panel. -> System -> Hardware tab -> Device Manager button -> In Device Manager, select View from the toolbar and then click Resources by Type. Clicking on the Interrupt Request (IRQ) you can find IRQ settings for various devices in the computer. If you see a conflict. You can right click on that device and go to Properties. Under Resources tab you can see the IRQ settings among other properties. Here for a conflicting device you can deselect the Use Automatic Settings option. After this you can select a non-conflicting configuration from the pull down box and save by pressing OK. For some system devices the operating system may not allow you to change the settings.
In the context of computer systems, IRQ (Interrupt Request) lines are used by hardware devices to communicate with the CPU. However, there might be instances where you'd prefer certain devices not to use IRQs. If you wish to prevent a PCI (Peripheral Component Interconnect) device from using an IRQ, you generally have to go through the system's BIOS (Basic Input Output System) settings. The BIOS interface varies among manufacturers, but usually, you can access it by pressing a specific key (like F2, F10, or Del) during the system startup. Once in the BIOS settings, look for options related to IRQ assignments for PCI devices. This setting might be under different menus based on the specific BIOS version. Once located, you can change the IRQ settings to manual and then disable the IRQ for the specific PCI slot. Remember that changing BIOS settings should be performed with caution, as incorrect configurations can lead to system instability. Always ensure you understand what each setting does before making adjustments. Also, refer to your motherboard's manual for specific instructions.
PS2 is the input format for the mouse, optical refers to the 'laser mouse' method of mouse movement. PS2 is an old format which is not supported by many newer computers, as companies favor the USB input format since it allows for faster data transfer.
IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports IRQ 4 - COM1 (Default) and COM3 (User) serial ports IRQ 5 - LPT2 Parallel Port 2 or sound card IRQ 6 - Floppy disk controller IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9. IRQ 10 - Free IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor IRQ 14 - Primary IDE. If no Primary IDE this can be changed IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html

yes.. only you have to connect it in usb port..
Try resetting back to your default mouse settings, no custom cursors or anything. If that doesn't work go to 'Options' then 'Custom Settings'. Then change your mouse settings.
IRQ 3.
LTP1 should use IRQ7.
