Hi friends, could you please recommend me a powered USB hub in Australia(preferred in Melbourne)? I guess my problem is caused by the insufficient power supply.
I have a FEZ Hydra Basic kit. I got it in 2012 (might be in Sep).
Today I downloaded the latest SDKs, drivers and everything(NETMF and Gadgeteer Package 2014 R1). (.NET Micro Framework 4.3 and the firmware I have on my laptop is 184.108.40.206)
But the firmware on my deivce is 4.1.x.x(I was lucky to saw the device’s firmware version just once and I followed the instruction on the software FEZ Config, but failed with errors).
After that, I cannot get the Device’s firmware version any more.
I found changing USB ports sometimes help. I have 4 USB ports, some of them can connected to the device, others are not.
So I have no idea to update the firmware in other way.
Could someone please help me to figure out how to find a way to update my firmware?
In the attached image, it shows: the FEZ Config detected the FEZ Hydra and was trying to get the device’s firmware version, but it failed to do so and followed by an error message say: Failure - Device is not connected or not responding.
As I mentioned above, I was lucky to see the FEZ Config successfully got the device’s version only once.
So my guess is - is it because the output power is not strong enough to support the operation, so I have to use something like a USB hub which has a strong and stable power?(I saw someone mentioned this and cannot find the comments any more).
Bt the way, all USB ports I mentioned above are directly on my laptop which means they get power directly from motherboard, so they should have strong and stable power to support my operations.
I have been stuck at this issue for the whole day, I really hope some friends can help me out.
Thank you very much in advance.
