I used this one for a while and did not have any problems with it
but internally it is actually two hubs chained together so when I had it connected to the Icron REX I could only use 5 of the 10 ports as the remaining ports exceeded the max number of USB hubs you can have in series.
I switched to this one which I have been very happy with:
One nice thing is that it takes 12VDC input. For the old one I had to use a 12V to 5V converter which I was happy to toss out when I switched to the new one.
It’s a little pricey but works extremely well. It requires power supply using any voltage from 5.5VDC to 30VDC. I connect my 12V marine deep cycle battery to this hub. Make sure to get the “non-captive” one. “Non-captive” means it uses Type B USB connector instead of “captive” which is six feet USB cable permanently connected to the USB hub. Personally I prefer “non-captive”. Amazon.com also sells it. The part number is 301-1010-74.
I connect 35 feet active USB extension cable in between laptop and this USB hub. From USB hub connects to 4 of my astro-devices.
I’m not sure what you are asking there. Could you clarify?
I use the Icron Ranger 2212 USB extender with the startech 7-port 12V powered hub at the mount. Actually I got the hub from here but I think it is the same device as the startech.
Andy,
More of a comment.
I have an Icron extender, a friend bought a Startech extender.
They seem to be identical units with different branding.?
So one could assume that the quality of construction in the hub would be about the same.
I have conducted no electrical measurement though, do not have the equipment for that
This is what I use too at the moment, it is powered by a 12V- 5 V DC module at the USB port end. 4 USB ports are insufficient for me though - so I have an industrial StarTech 4 Port USB2 to expand, powered with 12V. The Lodestar runs from the Paramount MX’s own powered hub, connected to the StarTech. When I go remote with the NUC, I shall remove the StarTech extender and feed USB directly into a 7-way Industrial Startech USB2 hub and onto the Paramount, removing a hub in the chain.
That is pretty much what I am using but mine is an Icron, I believe they are the same unit just different branding.
I have pretty much narrowed my problem down to my powered hub.
After taking the Icron out of the system I was able to be successful using just a short USB from the hub to the laptop, but only when using the 110V adapter. If I switched to my 12v deep cycle (13.4V) I would lose the lodestar, so it seems to be very power sensitive.
I have the Startech 7 port hub on order, in fact it shipped today. I am really hoping this solves my problem with my extender.
For what it is worth, I used to use two extenders that were USB 1.0. One was an Icron, the other a Gefen. They looked the same except for the paint job. One day I mistakenly connected the LEX from one to the REX from the other. It still worked fine.
Now I have both a Startech USB 2.0 and an Icron USB 2.0 and they too look identical except for the color of the case. I have not tried one with the other but would be surprised if they were not the same. Plus the Startech was cheaper.

My problem continues.
As usual things work very well straight USB with no Cat5.
I have, tried a friends Startech 2004 same issue.
I tried his Lodestar camera, no joy.
A multitude of different cables…
I did replace my powered hub with the Startech 7 port industrial (nice hub) same issues.
Started experimenting as the weather is so poor lately>
Connect PHD2 and start capturing good for 40 minutes.
Open SGP, do not connect anything, good for another 10 minutes.
Connect the QSI/Filter combo, good for another 10 minutes.
Connect the Moonlite DRO focuser>> camera (Lodestar) locks up in less than 60 seconds.
This will happen on my Laptop Win 8.1 64 bit, and my Desktop Win 7 32 bit.
Icron did send me a firmware upgrade for my extender , so I will try that next.
It is previously owned and the SN was not available, so firmware status is not available.
I am not optimistic, as the Startech extender exhibited the same problem, and it is almost new.
I do of course suspect the Moonlite driver, but I am not sure I have a lot of options there.
I have uninstalled and reloaded it more than once.
I may be stuck outside for a while from the looks of it.
I’m running very similar hardware, Startech USB over Cat 5, Startech 4-way industrial hub, Lodestar, QSI 683 etc.
I was using the SX driver 1.2.0.1 - but for some insane reason, felt compelled to upgrade last night to 1.3.2.1 on Win 7 -64 bit. I had very similar issues to you with SGP apparently not working with PHD2. Actually, PHD2 couldn’t even cycle properly. I reverted to 1.2.0.1 and everything worked perfectly (as it had done since SGP started on 2.4 beta’s back last year.)
1.2.0.1 is still downloadable off the SXCCD website
Buzz,
I think that was it, just went 15 minutes of capturing with the Lodestar, everything connected up and running.
No lockups. My previous times were anywhere from 30 secs to 5 min and 12 sec., Average 2 min 40 secs.
Whew, as soon as the clouds move on out I will do an extended test while imaging.
I am just a bit thrilled with this
Thanks a million, really.
