Device no detected in COM1

COM1 and COM2 refer to a computer's communications, or serial, ports. COM1 ports are often used on older PCs to connect network devices, digital cameras and mice. Faulty drivers software that enables the hardware to communicate with the operating system or incorrect hardware configuration can influence COM1 behavior. In rare cases, the expansion card that adds the serial ports to the PC can fail, rendering both COM1 and COM2 ports useless. To repair a COM1 port, you must determine what is preventing the port from working before attempting a solution.

Click "Start." Go to "Control Panel" and then click "Hardware & Sound." Select "Device Manager" from the submenu. Expand "Ports (COM & LPT)." Double-click "COM1." Review Device Status on the General tab to check for problems with the software driver. If the message "The Device Is Working Properly" appears, click "OK" to close the window; otherwise, look up the error message on Microsoft Support. Follow the directions in the Knowledge Base to correct the issue. Press "Alt" and "V" to open View. Scroll to "Resources by Type." Press "Enter." Double-click "Interrupt Request (IRQ)" to see a list of devices. Double-click "Communications Port (COM1)." Check the term to the left of COM1 to see if the card uses an ISA or PCI interface. If the card uses a PCI interface, it can use the same IRQ as another PCI device without producing a hardware conflict. If the device is ISA, it needs its own IRQ. Go to the "Resources" tab. If "No Conflicts" appears in the Conflicting Device List, close the window; otherwise, uncheck "Use Automatic Settings." Click the drop-down menu and select each configuration until the port no longer interferes with another device. If conflicts occur with each configuration, double-click "IRQ"; you may need to try different configurations before Windows gives you permission to edit the interrupt request. Click the up or down arrow to change the IRQ until the message "No Devices Are Conflicting" appears in the Conflict Information field. Click "OK" to close each window. Click "Yes" when prompted. Connect a device to the COM1 port to test the port. If the device doesn't respond, shut down the computer and then unplug the power cable. Disconnect all devices from the back of the PC. Remove the case cover and touch the computer's chassis. Set the computer on its side so that the PCI and ISA cards sit at a 90-degree angle to the floor. Find the serial ports on the back of the PC. Look on the opposite side of the case to find the associated card. Shine a flashlight onto the card and make sure that the copper contacts are not visible. If you can see the contacts, reseat the card in its slot so that it's fully installed to the motherboard. Reassemble the case and boot into Windows to test the COM1 port. If the port still fails to work, you may need to replace the serial port card.

Windows 95 does not support flash drives on an AT machine.

You need to make sure you have selected the correct COM port whin you try to print. Depending on the type of USB to serial converter, the COM port it assigns can change just by moving it to another USB port. Right-click on My Computer and select MANAGE. Select Device Manager from the list. Click on the (+) next to PORTS and double-click on your USB-SERIAL device COM port. Somewhere in the Properties window you should be able to see the assigned COM port (COM1, COM2, etc.). If possible, set the COM port to COM1 or COM2 for greatest compatibility with older software. Then when you print, make sure your printer driver is also set to the same COM port.

hi,
1) right click on my computer > click on manage. 2) you will see computer management window on left side click on device manage. 3)click on universal serial bus controller
if you see yellow color acclamation mark then their issue with driver and check you have xp SP3.
to check that right click on my computer>click properties. when a windows open you can see computer information you can look there you xp or xp sp2 or sp3 check below Image

if you don't have then download from microsoft.com.

check the com port of the appliaction, it is based on com1 only then you will need to make changes to the com4 to com1 follow these steps
open device manager
choose com4 and then right click for properties
choose port settings
choose advance
change the port number from 4 to 1
that will be all you can now give it a shot again

On some computers the output power of the USB ports is too low to drive the Ext. HDD.

Have you tried other USB ports on your computer?

Get yourself a powered USB hub and try that, borrow one if possible, if that works get one for yourself....

You need to manually setup the serial printer, as it probably isn't getting detected via plug n play:

• Go to Start Menu\Printers & Faxes
• Click on the 'File' menu and choose 'Add Printer'
• Click next at the wizard, then select 'Local printer attached to this computer' and leave the 'Detect Plug n Play...' box unchecked, click 'Next'
• Choose the correct serial port (either COM1, COM2, etc), click 'Next'.
  
• Choose the correct printer manufacturer & model to install the correct driver, click 'Next'.
  
• Print a test page, just to make sure it's working
  

Yes. com1 Should be labled Serial Port on the PC.

The problem was not the topaz pad but my laptop. I removed all software which needs the serial port and I finished all not necessary programs which were running in the back but the problem was still alive. Now I asked my administrator for more rights and I changed the name of the port from port "1" to port "3" (port "2" doesn't work). I've got the message "port 3 is already in use" but the pc accepted the exchange of the name. Afterwards I changed the portnumber in the ini.file of the Topaz Software and now it works without any problems... strange, strange.... my five colleagues who are using the same pad on the same type of laptop (Compaq nc 6120) haven't got any problems during installation of the pad.
Thanks for your interest - kind: regards Ben Gun

install the vendor specifig driver for the PCMCIA. because windows XP sp2 is also able to detect the device and when you push the device online it is detecting and there is some other device which has got same IRQ and that is conflict with this and stop. see any error that is generated in event viwer * run>type "eventvwr" and enter * see the application/system try to detect your error log and see what microsoft says about it. otherwise post the error report Thanks Arun
