USB microphone not recognized at startup
Submitted by snsok on Tue, 03/25/2008 - 15:46.
IBM Thinkpad T60, WinXP SP2 on a business network, Philips Sopeechmike USB 6274
A minimal but chronic vexation: When I start my computer and load DNS at startup, my USB speechmike is not recognized by the system. I ahve to unplug the mike's USB plug and reinsert it. Then I get the satisfying "connection" beep from both the laptop and the speechmike.
My other USB devices seem to attach OK at boot-up (printer, digital pen cradle, PDA Active Sync, etc.
Any fix for this?

This is pretty unusual behavior for a USB device, even a microphone.
The first thing I would try is inserting the microphone into a different USB port at your next startup. IBM's are uniquely than other notebook computers and there may be a priority to certain USB ports.
One other thought comes to mind. Are you starting from the computer being totally off or from sleep/standby mode? I have seen this behavior from sleep/standby mode.

Just adding to Martin's excellent advice...
as a last option you could wait for your computer to boot, plug in your
Speech Mic and then launch NaturallySpeaking.

Further to my previous
Further to my previous posting, I should add that I have had more continuous problems with the USB connection for the SpeechMike in my laptop.
Frequently, I use my mouse to click on the microphone in the speech bar (were I either have it on or off, but never use sleep), and after a couple of clicks, the SpeechMike starts working again.
When it becomes completely obstinate, I disconnect all my USB peripherals. Using Control Panel \ System \ Hardware \ Device Manager, I uninstall all my USB Root Hubs and Host Controllers (using the touchpad mouse). Then re-boot and at the same time connect my USB peripherals, and XP finds all hardware and installs necessary drivers.
This usually keeps me going for a week or two before I have to do this again.
These problems never arise on my desktop computer.

Well, just using a different USB port made all the difference. Now the mike is racognized on startup. I had been using the USB port on the left side of the thinkpad. Now, I use one of the ports on the docking station.
Go figure. I thought all USB ports were the same.
Thanks

Well, you thought wrong.
Although USB ports are generally plug-and-play, they are sequenced and controlled not too similarly to the old serial ports. That is, they are numbered and they do have their priorities.
In your case you are using a docking station. Docking stations have different configurations depending upon the make and model (i.e., laptop). In some cases, the system only allows the USB ports on the docking station to be active. In others, the docking station USB ports become the primary and the laptop USB ports become the secondary. Secondary ports are generally problematic with regard to hardware such as microphone inputs for DNS. Therefore, I'm not surprised that you had to switch ports in order to make it consistently recognized.
Also, not all USB hardware & drivers are created equal either.
