I can't find com ports in Device Manager. Trying to interface with a counter digital multi via a RS232 connection.
The software supplied with the meter has enough summary documentation. When I tried to open the software, a window pops up saying that the port com 1 cannot open. I used baud rate settings that the software manual recommends but no help. Then, I uninstalled the COM ports. Now they are gone and I don't know how to re - install.
UPDATE: I've read elsewhere that the BIOS should have the com port activated, so I went into the BIOS and of course it was off. I suspect that it is off all the time, because the software failed to connect to it when I first installed it. As soon as I have it set to com 1 everything works.

Last version of Firefox is installed on both devices.
I guess that what I read on this forum that the problem may come from the Tablet (Samsung) who may have the old version of sync. I deleted the Firefox sync account on it and installed the latest version of Firefox, but then when I want to add the Firefox sync account, I get the 3 codes I'm supposed to learn about computer synchronization options. But the computer does not provide this option. Can you please help?You need a Firefox 29 or later on this tablet in order to connect to the new synchronization version.
The 'code 3' 'twinning' function last used in versions of Firefox 28 on all types of devices. And it's sounds like this tablet has a pre-Fx29 now version.

X 1 carbon Touch Fingerprint reader 'can not find the fingerprint sensor device' e7210005
Hi all
I have spent far too long trying to solve this problem by myself and need to reach out to someone who may have solved this problem. I read tons of questions similar online and restarted from dozens of times after trying many different things.
I have a carbon 3444-GCU Touch who can not see his fingerprint reader. It used to work when it is brand new, but after many updates from lenovo and windows, it now does not work:
I'm on Windows 8.1, with all updates.
No problem in Device Manager.
Coprocessor (WBF advanced mode) Fingerprint TouchChip installed under thin biometric devices.
_Not_ power management value disable device to save power.
The bios is 2.61.
I suspect that the problem is very low, because even the BIOS can not find the device trying to implement.
If I have the lates BIOS, but it can't see the camera - what can I do?
Thank you all...
you have a faulty drive.

Satellite 1700-300: No. Lan port in Device Manager
Hi Forum.
I am currently repairing a 300-1700-Sat and reinstalling windows ME (Yuk I know but that's the preference of customers), however it does not show that there is any ethernet on the system hardware. There is an ethernet port on the back of the laptop, but it just does not appear in Device Manager.
My first was, however, that it can be disabled in the Bios, I checked and there is no option for ethernet.
Any idea people?
Hello
I'm not an expert, but you are sure that the laptop has a LAN port to 100%?
The laptop is an oldie. That's why I didn't find a lot of information in the internet, but I studied a bit and found that the device supports only:
Parallel port, PS/2 mouse or keyboard, 2 x USB modem RJ11, speaker/headphone, microphone (no internal) port, PCMCIA port and external monitor port of CRT.
There is nothing of LAN port -

Can someone point me in the direction of this driver please?

You can find more info on the device if you go into Device Manager, click on the PCI Serial Port and click the Details tab.

I have been using the Robinhood app for stock trading. Today, it is very buggy, AND I can't find it in the app store! Everyone knows about this problem?
If you can't find it in the app store that he may have been drawing.
Did you check all aspects of the app store? For example, there are a few applications iPhone or iPad only, and so that they could be installed on another device still appear in only part of the store (before it became a universal app, I could install instagram on my iPad, but it was listed as an iPhone app appeared only in this part of the store)
Did you google the app to find the page of the developer to see if there is any news there?
