USB2 devices plugged into 1600MM port

Postby JamesRC » Fri Dec 01, 2017 3:59 pm

The 1600MM COOL is a USB 3 device and has the correct cable for that use. However, if I have a USB 2 guide camera plugged into one of the USB2 ports on the 1600MM, does this effectively make the camera a USB 2 device also? I hope my question makes sense ;)

Sorry if that USB3 vs USB2 question sounds witless. When I have my USB2 guide cam plugged into the 1600MM's USB2 hub and then plug the 1600MM USB3 into my laptop's USB3 port, I get a message suggesting my computer sees it as a USB2 device.
That's all! :oops: :roll:

This problem still happens, but independently of the guide camera. Problem may be in my laptop, An Acer, because it can't recognize the ASI1600 as USB3 no matter how I connect it. The same port on the computer works fine with a USB3 stick. :cry: :o

I am giving up this topic, this has turned into a really weird problem that I think is related to the USB system or circuitry on my laptop. The 1600 works, then it doesn't. its recognized as USB 3 and then recognized but marked "device cannot start" and then it works again. Not all at the same time, but as I go about trying to track this down.. At least, the ASI1600MM is innocent :lol: It works fine on 2 other computers, a big desktop and an old, slow laptop. Maybe conflicts with my 120MM guide camera, sometimes but not always. Gosh.

That is all of this, from me.

I use a ASI120MM plugged into my ASI1600MM-C (as well as a USB-RS232 adaptor for the mount), though my astronomy laptop only has USB2 ports. To get the two cameras working together I had to reduce both of their USB bandwidths to 40%.

As with any hub, the one on the ASI1600 will only run at the lowest standard, so if there is a USB2 device plugged in then the ASI1600 will only communicate with the laptop at USB2 speeds, that's the main reason I haven't updated my laptop.

James, thank you!

This pretty much confirms what I have been suspecting. I was afraid it sounded foolish :oops: :roll:
I was also having problems with the general fickleness of USB devices.

I guess I can plug my guide cam into a USB2 port on my computer and the 1600MM into the USB3 port and get the higher speed.

Thank you very much. :D :P

What is the correct connection for a the ASI 120 super speed and the ASI 1600 pro? Both are USB 3.0. I have 1 USB 3.0 port on laptop. The USB "IN" and "OUT" ports on the 1600 are confusing and don't make sense to me.
