Re: USB2514B on Win10: Insufficient system resources exist to complete the API.
Thanks for the reply. I thought so as well. However my intuition as a user is that since every USB port is capable up to 500mA, hence i thought that a usb hub downstream a host port should still support 500mA active total since the host monitors the current supplied. What i don't understand is why there is a specific 100mA limitation per port..i guess USB spec, right? If that is the case technically all external usb hubs should be externally powered so that 500mA per port is available.
Anyways my device is just a custom keyboard that has an integrated hub. 1 port is connected to the controller and 3 ports are available to the end user. (supposed use: 1 mouse + 1 usb mic + 1 usb flash drive). I should be more worried reaching the current limit due to all RGB led per key haha.
I've also tested the performance of the hub and measured no speed difference. I'm very satisfied :)
Also the E2PROMAPP makes it a breeze preparing an EEPROM file :) However just by pure luck in the forums i found out that USB2534 is a direct replacement of USB2514B which has internal EEPROM. It would be nice to know beforehand, it simplifies some things and has more features.
Currently i'm also using a USB switch, EEPROM and a 3.3V LDO from Microchip in the same project and i'm pleased with the quality and functionality of Microchip's products so in the future will definitely look first here :)
