You shouldn't need multiple instances of cgminer. The current version of cgminer works fine with both of these devices at the same time by default without any special flags or multiple instances.
My rig is now running smoothly with a single instance of 4.2.1.
I had the same problem but used a different approach:
I've changed the internal USB serial number using Silabs' CP21xxCustomizationUtility (which is available in AN721: http://www.silabs.com/Support%20Documents/Software/an721sw.zip) to, let's say, 1337.
To detect which device number my U1 is, I'm executing this command:
This will output something like this:
And bingo, there's the device number which I then use for cgminers' --usb switch.

Code:
dmesg | grep "SerialNumber: 1337" -B 5 | grep "device number [0-9]*"
This will output something like this:

[ 5753.262747] usb 1-1.3.1.1: new full-speed USB device number 13 using dwc_otg

It does get hot.
Hotter than normal? Could be a short circuit then. Measure the resistance between VCC and GND.

Daraus habe ich erstmal ein kleines Diagramm der Speed im Verlauf der Zeit gemacht.
Re: [65000 GH/s] Slush's Pool (mining.bitcoin.cz); TX FEES + UserDiff; ASIC tested
While merged mining is not supported anymore, is there any chance of getting my remaining NMC's out of the pool?
only if it more than .05 NMC if so, just change the distribution threshold.
It's actually below 0.05 NMC.
...plus as USB hub controller...
What controller IC are you using?
Great eye. You [both] win three internets and a kitty. Amazing.
Yay!
I assume that it is to power the on board Linux OrSOC device?
It looks like a Beaglebone. Further, the cut-out to the left looks as though it might be for a rPi.
You could be right, here's a comparison:

Also note the round edges.
The icarus driver does infact re-calulcate the timings, if the hash rate is below 370 or above 420 MH/s.
Re: Offizieller ASICMINER Block Erupter Europa thread - usb ab 0.4 | blade 12,5
Nochmal: Muss ich nen ATX Netzteil zerruppen oder gibt es eine elegantere Lösung?
Stückchen Draht am ATX-Stecker zwischen PS_ON und GND, und schon läuft das Netzteil, auch ohne Computer.
Re: Offizieller ASICMINER Block Erupter Europa Info & Verkaufs- thread - Preisupdate
Wie gesagt, sobald ich wieder Geräte habe geht es weiter. 
Steht direkt eine Zeile darunter.
Nachdem wohl doch Bedarf an pre-order besteht testen wir des jetzt mal mit den blades (alte version)
12,5 BTC

Wo wird denn der Unterschied zwischen old und new blade sein?
Angeblich USB statt Ethernet und 13 GH/s fest ohne Overclocking.
Why even bother to link that? It's a copy/paste of the OP from this thread.
It's spam. Compare the username with the URL...
Ausnahmecode: c0000005
Das ist STATUS_ACCESS_VIOLATION, also versucht cgminer auf Speicher zuzugreifen, auf den das Programm aber nicht zugreifen darf. Hört sich für mich nach Bug im cgminer an. Hast Du es schon mit einer neueren Version probiert?
