Single-Use Camera Reader for Windows

Single-Use Camera Reader, as the name implies, is software that allows you to read picture data from one or more types of "single-use" digital cameras currently on the market. It is known to support the SPCA504b-based Dakota Digital Camera (PureDigital Technology), but according to this, not the Walgreens single-use digital camera.

Beware, some (many?) of the Dakota cameras being sold now are the new "PV2" series (both with and without color LCD screen); these are based around a completely different chipset, and are not compatible with SUCR. These can be identified by the new case style and the 'PV2' displayed on the camera and packaging.

The program allows you to read picture data, clear the camera (for reuse), view basic status and hardware information (such as firmware version), and dump the raw contents of the camera's internal memory. Future versions may allow you to do additional things such as upload custom firmware or send raw commands to the camera.

Download Single-Use Camera Reader

Current version (0.05) with LibUSB-Win32 version This version corrects a bug that prevented more than 127 pictures from being correctly downloaded. Yes, now you can actually store that many pictures under certain conditions :-) See the readme for details.

Current stable version

The USB requests should be pretty self-explanatory with the help of good documentation.

Reporting Bugs

The Single-Use Camera Reader bundle consists of two different pieces of software: there is the reader itself (sucr.exe), and a set of driver software (libusb-win32) for talking to the USB port. Single-Use Camera Reader is written by me, and libusb-win32 is written by Stephan Meyer and probably(?) others. If you experience problems after installing the libusb drivers (such as any blue screens, hangs, etc.), please fill out a bug report to the libusb-win32 developers using this form. If you experience problems in the sucr.exe program itself (such as program crash, picture download fails, etc.), e-mail me. My e-mail address is at the very bottom of this page.
I will be unable to help with or correct bugs in libusb-win32, and by the same token, the libusb-win32 developers definitely will not want to hear about how you cannot download pictures! So, please follow the above when trying to determine where to send a bug report.

Walgreens Cam?

Sorry folks, it looks like the Walgreens cam uses a different (unknown) command set; Single-Use Camera Reader doesn't speak it. I don't have one (and since I have a couple of Dakotas already, don't have the inclination to go buy one and try hacking it), but if some enterprising hardware hacker is able to figure out / document the command set, I'll be happy to add support for this cam.

Troubleshooting / known issues

Previous SUCR v0.04 release:

The previous release of SUCR 0.04 featured incorrect instructions for installing a libusb-win32 package. (It directed users to an .EXE installer for a filter driver, not a stub driver.) This is corrected in the current release; back to right-clicking and "install" on the .inf file. Stub drivers are now again packaged with the SUCR release. Windows (All versions):

If upgrading from an old release of libusb-win32 ( or before) to a new version ( or later), Windows may not detect the camera's interfaces as separate devices (e.g. USB Composite Device, Bulk, ISO).

Windows (All versions):

You receive a "sanity check failed" error while downloading pictures.

Windows (All versions):

Camera plugged in, but not detected even after installing the drivers and REBOOTING.

Windows XP:

After installing the libusb-win32 drivers on some Windows XP systems, Windows hangs on shutdown or takes an unusually long time to shut down.

The following problems are believed to be fixed as of sucr.exe 0.03 and libusb-win32, but are retained for reference.

Windows (All versions?)

Problem: When attaching the camera for the first time, Windows may detect your camera as a "Composite USB Device" and automatically install a generic driver, rather than asking you for the LibUSB stub driver. Then, it will detect each of the camera's USB pipes as separate devices, and thus ask for (and install) 2 copies of the stub driver in addition to the "Composite USB Device". NOTE: This is correct and expected behavior as of version 0.03 (libusb-win32 version!
If this happens on older bundles, however, the camera will not be detected, and you may get a bluescreen when running sucr.exe or testlibusb.exe.

Windows 98 and 98SE

Problem: If installing the stub driver, Windows may report that the .inf file could not be copied even though it may have copied correctly. This is a known issue with the .inf file supplied by earlier versions of LibUSB-Win32, and is (hopefully) fixed as of version included with this release.
