Error code 8

Has anyone else tried a different industrial grade USB hub like Siig, Blackbox or Moxa to see if the error code 8 issues go away with a better hub? I am considering this, but those hubs are listed in the $300+ range and if they do not work I just tossed more money onto this issue. I already bought a second StarTech to give my STF it's own hub and the issues still occurs.

 

Im about to rewire my whole observatory and install a new computer. ID LOVE to have just one hub on the telescope back for all the equipment. Can I use a startek industrial hub now? Or is this problem still present?

 

looking at this one:

Hi Brian, yes my problem was still present, but the problem may come from my extender because I decided to install a computer in my observatory and so I have direct connections to the computer with usb cables 15 feet and I no problem now

 

In my case the computer is right next to the pier with a startech hub on the telescope. I currently have a dedicated USB cable for the STF-8300M. Ideally when I rewire it, I only have power and 1 USB going to the telescope.

Thanks for the reply.

Im really wondering if Diffraction Limited solved this problem which seems to be specifically with certain USB hub chipsets.

 

Thanks for the reply.

Do you think a startech USB3 hub would exhibit the same issue? Surely it's a different chipset entirely. OR is it an issue with all hubs. If not is there a known good hub (especially industrial, because the Startech ones have extended temperature range. My observatory can be anywhere from -10 to 90F

 

I get the sense that nearly all the "industrial" hubs Ive seen are basically the same, rebranded units. Even startech sells a wider range temperature unit, but it looks like it has some sort of active heating/cooling added to the same chassis. I guess for now Ill run a cable. Thanks for replying.

 

Is there any update on this? Id really love to use the STF8300 on a hub. Particularly Im looking at several mounts that include hubs for cable management reasons.

 

"Bryan - what are you looking for from us? We don't make hubs." Thanks for that. Great customer service. I was looking to use my STF8300M on a hub. A pretty straight forward ask. So it's the company's position that this camera is designed to go directly to a computer only? I had it on a hub for a long time, this hub died and I don't have it anymore. Any subsequent hub Ive tried has exhibited the error. I have other brand cameras with hubs built in even that work on hubs. I guess it's about simplicity of wiring as my setup is already too complex. If I were to get a mount with built in hub, I would have to add a separate cable just for this camera. My older St4000 series camera also didn't have this problem and I suspect newer cameras also do not. So the reason for asking is: Adam stated: "We believe the communication issues we see most commonly with hubs has something to do with our low-level driver and malformed USB packets, but we won't know for certain until we can evaluate an updated version of our USB chipset drivers".


Seems to be an admission that the problem is with your software/driver/hardware somewhere. Id like the camera to work as it should.

 

Thanks.. I have the USB3 version of that hub ST7300USBM. So you're saying with the latest firmware/driver the ST7200USBM should work?

 

Salutation, to update this publication I corrected the problem by installing a computer in my observatory and connect the camera directly on the pc with a cable of 10 feet, my extender usb of $ 600.00 does not work since with this camera, all my accessories works well but not the sbig, my pc and a tower with more than 15 usb ports so now for me hubs and stuff like that, the direct connection is the best solution to a lot of problems, I've been doing this since over 4 years old and i have not had any problem since !!!!

 

While I have not seen any issues with our STF-8300M cameras (possibly because these came after my solution), I did see the same problem with the original ST-8300 when connected to either a standard 2.0 hub or powered hub. The distance between the 0.5-m telescope and the control room is about 20 feet. My solution, which has not failed since, was to purchase a 30 foot Active USB 3.0 cable from Amazon. An STF-8300M, ST-8300 and STX-16803 (1st Generation) are all attached to a non-powered hub, which is carried to the control room with the active USB cable. Most active cables shorter than ~50 feet typically don't require an external power source making them perfect for our observatories.
