Thank you for your patch, but the same problems occur with the patch applied. => log attached
=> "xHCI xhci_drop_endpoint called with disabled ep"-messages, ...
Do you know why the lspci output shows different capabilities/features/flags with the same NEC Controller (exact revision), but different connection/interface? PLX Chip with NEC: not working, PCIe-card with NEC: working
Here are the differences between the lspci outputs;
PCIe Type | CacheLineSize | Flags; AuxCurrent | PME |DevCtl | MaxReadReq |AuxPwr | CommClk
-------------------------------------------------------------------------------------------------
PLX Chip, NEC, problems | 32 | AuxCurrent=375mA |D3cold+ |NoSnoop+ | 512 bytes |AuxPwr+ | CommClk-
PCIe-Card NEC,working | 64 | AuxCurrent=0mA |D3cold- |NoSnoop- | 128 bytes |AuxPwr- | CommClk+
Best regards, Bernhard

Could you try if disabling all LPM related control transfers on the buggy NEC hosts has any impact at all.
If you can, please apply the following patch and see if it helps:
