Just to give you a follow up. I contacted the Digikey support that directed me to a Taiwanese support. After a quick test appeared clear that the MicroUSB socket was broken , they offered me to repair it with shipping + maintenance charged on me (which is totally fair) , after a quick check I realized only the shipping would be costing me around 70 euro (I payed 110 euro for the DE10 nano) so I contacted again the support and they offered to ship the socket which costs around 0.1c + 35 euro of shipping cost (!), I asked whether I could buy the component myself since it appeared quite standard , they replied that of course was possible , the component is:
MICRO USB AB TYPE, FEMALE SMT 5P(RoHS)(UMMUF-051MGCB1-CF1108)
I found a technician in a local mobile phone shop that claimed to be able to do the soldering and.. it worked !
I spent a grand total of 59 euro (which is kind of a flat rate for them)
next step is to buy a proper USB OTG HUB (lesson learned)
hope this will help someone someday
