Windows 11 doesn't recognize EOS Ra

srchilders928 — Fri, 15 Apr 2022 19:17:54 GMT

I have a new PC with Windows 11, and I installed EOS Utility 3.15 for Windows. My 7D Mk II connects perfectly through this version of EOS Utility, but EOS Utility does not recognize my EOS Ra. The computer does see the Ra; it shows up on the Device List as Unknown Canon Digital Camera, whereas the 7D Mk II shows up on the Device List specifically as the 7D Mk II. I have no problems connecting both cameras on a Mac through its version of EOS Utility. Anyone have any ideas? I am new to Windows, so maybe I'm stupid.

Is there a particular reason why you have to use the Canon Utility - what are you trying to achieve with the program?

Yes. I have to do remote bulb shooting for astrophotography. There is a Windows app, Backyard EOS, that does the same thing only much better, but it is showing the same exact issues with the EOS Ra (but not 7D Mk II) that EOS Utility does. I'm assuming that if I can fix one, I will fix the other.

It seems like this is something specific to the Ra, and very few of us have that technology. I would encourage you to contact Canon's help line for some expert help on that one.

What brand of computer do you have? Prior to the release of Windows 11, many users reporting issues with running Canon apps that connected to cameras via USB were not using Intel chipsets.

I have not checked, but does your version of the EOS Utility support Windows 11?

It could be unique to the Ra. But, I do not think that is very likely. What sets the Ra apart is mostly the sensor filtering and the firmware. USB ports are probably identical to the EOS E.

The 7D2 is an older body, which probably uses an older Canon chipset for USB ports. I am willing to bet that all of the more recent Canon releases will encounter the same issue.

The EOS Ra is basically an EOS R with a modified sensor and a couple of bells and whistles thrown in. In fact, Canon doesn't even use a specific manual for the Ra; they use only the standard EOS R manual. So I'm guessing that this problem would exist for the EOS R as well, but of course I could be wrong. But you're right: I should probably just contact Canon directly.

My computer is HP, with an Intel i5 chip.

According to Canon's pull-down menu for operating systems, EOS Utility 3.15 supports Windows 11.

"The computer does see the Ra; it shows up on the Device List as Unknown Canon Digital Camera"

Maybe someone on the forum that has an EOS R can see if they get the same error.

I'm having the same issue, I'm running Windows 11 with my EOS R. What's even more interesting is that if I connect it to my Asus laptop it works fine. same windows 11 and same OS Build.

The issue is almost certainly the name. There's absolutely no way your computer can tell what kind of filter is in the camera. But EOS utility almost certainly has a hardcoded list of camera names that it works with. "R" is on there; "Ra" presumably was forgotten, and since it's such a niche camera, no-one at Canon noticed.

Good news is that this can probaby be fixed by Canon just adding "Ra" to the list of supported cameras. But that would be work, plus testing, plus the release process. So it's still not very easy.

I can tell you what I discovered with my EOS Ra. Partly, it was a USB cable issue. My HP computer would not recognize the camera on a 6-ft cable, but it worked on a 3 ft cable. I am told that this may be a function of the quality of the USB cable as much as the length, but I don't know that. Also, I had to experiment with different sequences of connecting the camera. IIRC, the camera had to be turned on before connecting. It may also depend on the PC you use. One thing I know for certain: none of these problems occur on my MacAir. The Mac doesn't care what kind of USB cord I use, or whether the camera is turned on or not; it just works.
