Title: Im getting sick of the hardware gets disconnected.
Post by: Jordan on October 01, 2009, 06:08:57 PM
I have the box for only 2 months, and i wrote about it here after a week of purchase.
Its been happening WAY too much that the hardware just get disconnected, and no, the flourecent lights have nothing to do with it.
sometimes it happen 20 seconds after i disconnect and reconnect it again, and when i leave it on for a while when i leave the house, it can disconnect it self after 10 minutes, and the whole point of leaving it on (adding as many regs as possible to my log) is worthless.
if anyone can help i would appreciate.

My bet would be USB cable. What length USB are you using and have you tried another cable?

Your computer is defective. USB at these speeds requires good implementation.  I had to toss a computer that couldn't do wireless with a USB wireless adapter.  Just froze-up all the time.  My newer laptop has no problems with the same device.

It sounds to me like you may not have enough power going to the box from the USB port.

If swapping the USB cable makes no difference, then try swapping USB ports. Also if you some ports on the front on the front of the computer, and some on the back, then try swapping between them.

The other thing to try is unplug any other devices that are plugged into your USB ports and see if that makes any difference.

Just remember that when you swap USB ports, you will need to install the RB driver for that port - at least this is the case with Windows XP - does Vista or Windows 7 overcome this basic limitation?

Are you sure about this?

I've never specified a particular port when installing USB drivers, and my RB gets plugged into different ports on my netbook with no problems.

Certainly I've not had driver problems with my XP.  Any port available for me and the PC recognises the hardware immediately. This applies to any other hardware using USB connection.

Following up on what Jez says about limited power, I would recommend an active USB cable. They work really well and give you freedom to put the box virtually anywhere.

Shop around on Ebay for best prices.

No issues with Vista - got 4 to choose from and dependant on where my laptop is, I have used all
No significance with initial set-up either

hope this helps wrt Vista?

Hence my posting on the Lindy product, definitely get about 35% more a/c running the RB off the remote psu than from the lap-top directly.   Range with Glyn's bog standard antenna upto 250nm out over the Atlantic, it'll be interesting to compare with the SSE 1090SJ MkII that I've now received.   Also, have no issues changing USB port running Vista.

Yes, when I swap USB sockets on my desktop or laptops running XP, I get the 'found new hardware' message if I haven't used that device on that port.  If you don't get the problem, then don't worry.

Im using the supplied USB cable.
Im using the same USB port.
I used the box for a month without anything else connected to the laptop, so i do nt think its a power issue, also, when it disconnects the blue USB LED is blinking every second, so it has power i guess.

I would still try another USB cable. There have been cases of faulty ones before.

The flashing blue light means that there is enough power to light the LED, but is there enough power to run RB?

Just confirm that you are plugging RB directly into your PC and not via a USB hub of any sort?
Title: Re: Im getting sick of the hardware gets disconnected.
Post by: Jordan on October 01, 2009, 09:55:31 PM
I assume it is enough since it is working + the laptop is connected to the AC.
Yep directly to the PC.

OK, on one of my laptops, although every USB port gives out 5V, they are not all listed as 'full power' by which I guess they are talking about current.  My portable USB DVD drive comes with a double-headed (2) USB plug and it will not run unless both USB plugs are inserted in 2 USB sockets.

Maybe try a different USB socket as well as trying a different USB lead?

The standard USB port will supply a maximum of 100mA until the device connected has negotiated the "high power" setting, which provides a maximum of 500mA. It's not that uncommon to find that something like a disk drive, which  needs more current to start up, will require two ports to provide the power it needs.

Dell Inspiron - says:

1 - USB Connector - connects to USB devices such as mouse, keyboard, printer etc

2 - Power USB Connector - this port can be used for USB devices that require more power.  This pot supports up to 2A current loading

I have used a Dell inspiron 1520 1525 1545 and a studio 1555 using vista and had no disconnections using version ANRB 3

The problem is, that not all USB2 ports are created equal across PC land. The supplied USB cable from Airnav is good. I have never had any problems with it.
On my HP PC. Even on my home built PC which is a few years old, the Airnav Box works well via USB.

And it was reasonably recently that I discovered that not all USB cables are created equal either!  I've got a couple of camera USB cables that don't seem to have the power pin connected - confused me loads!

I don't think it needs to be connected if the camera relies on its own internal power. Ground, D+ and D- are sufficient.

One other USB-related thing that bugs me is how my son's iPod won't charge with a standard USB charger, it expects the D+ and D- pins to be biased to half supply otherwise it doesn't detect the power supply is present.

Jordon, are you able to install the software onto another computer, a friends perhaps and connect the RB with all the original cables without any additional powered ports just with what came in the box.  At least you could then eliminate the computer issue, if the problem is still there then it must be the RB if not the the laptop must be the issue.

I agree. You need to go through a process of elimination which would eliminate PC and cables.  Just a thought - check your aerial input is secure, though not overtightened.
