Hi,
I could only identify this webcam by visual identification of image on www.prevailingco.com under the type: P-PO359C. This website has no driver info or downloads. Emails sent to this site contact give no reply.
On the device itself is only mentioned: Modelnr. SZXL PC Camera.
There should exist a CDROM with drivers.
Can anyone help?

Support Information:
Device Type: Digital Camera
Manufacturer: Prevailing Promotion Ltd
Model: webcam: P-PO359C Modelnr. SZXL PC Camera
Interface: USB
Operating System: Windows XP Professional
Age of Device: < 2 years old
FCCID:

Find it on DriverGuide (http://members.driverguide.com/index.php?action=srch&sm=b&aax=&qa6=&qa5=2&qa7=1500&dp=2&qm0=webcam%3A+P-PO359C++Modelnr.+SZXL+PC+Camera&jmd=and&fzz=d) | Find it with Google (http://www.google.com/custom?client=pub-4727129938051271&forid=1&hl=en&ie=ISO-8859-1&oe=ISO-8859-1&flav=0001&sig=t06hRycrxd-fw_05&q=Prevailing+Promotion+Ltd+Digital+Camera+Prevaili ng+Promotion+Ltd+webcam%3A+P-PO359C++Modelnr.+SZXL+PC+Camera+Windows+XP+Profess ional+)

In the meantime I did receive a reply from prevailingco.com.
They send me a sofware which turned out not to be the driver but a videostream capturing soft developed by/with Macrovision :confused: .
I hope their next reply will have driver software on board.:rolleyes:

I received from Prevailingpro.com a exe-file which installed following files (TWAIN drivers...):
C:\windows\snp2std.ini
C:\windows\snp2std.src
C:\windows\system32\drivers\snp2sxp.sys
C:\windows\twain_32\snp2std\snp2dsc.ini
C:\windows\twain_32\snp2std\snp2TUI.dll
C:\windows\twain_32\snp2std\snp2std.ds

But when I connect the webcam, it does not find a hardware driver.
Do I need an INF-file?

thanks for any help
Louis

I finally resolved this :)
The webcam is not powered by Sonix hardware but by Z-Star Microelectronics (ZSMC) hardware type 0301.
2 drivers were available on driverguide.com which both work like a charm.

Prevailingco.com stopped being helpful after 3 email exchanges.
No further help needed.

Louis67,
Thanks for taking the time to document your experience. I'm sure it will help others with the same device and needing a driver. The 0301 chipset is a common chipset used in dozens of web cams.
