Problems with Windows Vista home premium digitus USB-serial-converter Propeller
![StefanL38](https://forums.parallax.com/uploads/userpics/798/nYUCW31ONX8OI.jpg)
Hello,
i'm using a DELL Inspiron 1721 Notebook AMD Athlon 64 X2 DUalcore TK-55 1.8 GHz with windows vista home premium
a Digitus USB-to-serial-converter with Propellertool V1.1 i still have problems
to find the propellerchip or downloading programs to RAM or EEPROM
i get errormessage no propellerchip found or porpellerchip lost on COM-Port 4
the devicemanager names the USB-to-serialconverter Prolific USB-to-serial-COMM
details: "ser2pl.sys" "serenum.sys"
How could this happen ? i thougt the download protocol is foolproof and frequency-indeoendent
who has a configuration under windows vista that works propely?
best regards
Stefan

I've tested the Propeller Tool v1.1 in WinVista Ultimate with the Propeller Demo board, but don't have a usb-to-serial configuration handy, though I wouldn't expect a problem.
Perhaps I should buy a Prolific USB-to-serial-COMM device and give it a try.
The download protocol is relatively frequency-independent, but there are still time-out possibilities on both sides (PC and Propeller)... this is probably due to some kind of CPU-time-jitter in the USB-to-serial-COMM's driver that it high enough to cause a timeout on the Propeller chip side.
Any suggestions on where to purchase the Prolific USB-to-serial-COMM adapter before I Google it?

thank you very much for the quick answer.
Wait a little bit. I'm just downloading the newest vista-driver for the USB-to-serial-converter
Then i will have to make windows do his MOST FAVORITE thing: RESTART several times until everything is done
I will post the result of this test
best regards

E3 = Thought
http://folding.stanford.edu/·- Donating some CPU/GPU downtime just might lead to a cure for cancer! My team stats.
it was a case of "never change a running system".
After installing the new driver nothing goes.
if i tried to reinstall the older i got an errormessage something was wrong with the inf-file
So i had to make a system-rollback before installing Propellerttol V1.1.
Install Propellertool V1.1 new and now it works "a quarter". This means one of five tries to download a program works.
if you really want to buy one here is the url

But i think it is a problem of the age of this old USB 1.1 converter Type DA-70145
So i'm only interested in a solid-rock-working solution
Which kind of USB-to-serial-converter works great with the propellertool?
My Dell Notebook has an expresscard-slot. Is an expresscard-slot the follower of PCMCIA-Slot ?
would an expresscard-to-seria-adapter work with no jitter at all ?
@RinksCustums
well i would like to use WinXP but there are no XP-drivers for the graphic
so you may suggest why did you buy THIS notebook:
it was the best compromise between price and features (1920x1200-Pixel-Display, WLAN, Bluetooth, 2GB-RAM, Accu for 4 hours) for 1066 Euro estimating 750 dollars

It would probably be best if you got a FTDI based usb to serial converter. They seem to work well in microcontroller setups (Basic Stamp, Propeller, Arduino, etc). I would choose Parallax's USBto232 adapter over an addon card.
