USB to Serial Cable Problem

[devfirat]

I have one USB to RS232 cable. I used it on Xp and Vista. When I set my system up to Win7 64 Bit it didn't work. I have a driver but Windows said 'it must be certificated' i use "Driver_Signature_Enforcement_Overrider" but it also didn't work. I opened device manager and i saw only Ser!...
What can i do??

Hi, I had the same problem with a DSO driver and after a load of aggrovation I managed to find a solution - http://www.mydigitallife.info/2008/02/26/unable-to-disable-integrity-checks-cause-drivers-not-found-in-64-bit-vista-x64
"readydriver Plus" worked a treat hope - it works for you  http://www.ziddu.com/download.php?uid=ZrCflpqlY6yimJunr6yZlJyiYa%2BWlZmn1

It looks like a prolific PL-2303, if you want to make sure go to device manager and advanced, and look at the product ID when it enumerates on USB bus, if the PID is 2303, the driver is READILY available, just google it for x64

hello guys, i've used that type of usb - rs232 converter cable once and i encounter an interface problem,
like it sometyms disconnect during the process, so i restarted the operation again, i used it to interface
serial on laptop.

do you also encounter the same problem?

regards...

I had similar problems with the old converter cables which were using PL2303 inside for conversion. I have also tried FT232. But now i prefer CP2102 from Silabs which is working better than PL series  and FT232 converters

How do you find the speed of these USB -> Serial converters?  I had to use one on a new laptop recently and mine is noticeably slower than another older laptop with serial built in. The exact reason I am not sure.

there are a number of common chipsets for usb to serial... as some have mentioned above, ftdi, prolific, silabs etc make various models. if it's made by ftdi (ft232 etc) you should have no problem getting drivers from their website. for weird chinese chips, problem is after win7 microsoft was kind enough to enforce stricter requirements on installable drivers and many vendors don't have updated drivers. first thing is to identify the chip used in your cable... you can use a linux livecd (linux will support almost every usb-serial cable/device) and run lsusb -vvv. a good start would be to write down the details and post.
