CgMiner 3.4 以前的版本看不到 USB Block Europtors (Windows)
自 9 月下旬以來，我一直在使用CgMiner 3.4.1。它可以看到我的四個 USB Block Erupters，並且可以正常工作：

3.4.1，忍受半日崩潰並且不得不記住重新啟動 CgMiner。今天早上我測試了 CgMiner 3.8，希望他們修復了它無法看到 USB Block Eruptors（以及堆棧溢出）。不幸的是，它仍然看不到 USB 設備：cgminer version 3.8.0 - Started: [2013-11-20 07:44:46] -------------------------------------------------------------------------------- (5s):0.000 (avg):0.000h/s | A:0 R:0 HW:0 WU:0.0/m ST: 2 SS: 0 NB: 1 LW: 16 GF: 0 RF: 0 Connected to stratum.bitcoin.cz diff 1 with stratum as user joesmith Block: 70bedfe6...

在 CgMiner 3.4 之後他們破壞了什麼，我該如何解決？
WinUSB
只是為了搶占可能提出建議的人，而不是提供任何見解，我重新執行了zadiag 2.0.1.162（更新於 2013 年 11 月 20 日），並為我的 USB 設備*“重新安裝”*了WinUSB驅動程序（並重新啟動）
沒有效果。
CgMiner 2.8 做錯了什麼而 CgMiner 2.4 做對了？
編輯：使用 Silicon Labs 自己的 VCP（虛擬 COM 埠驅動程序）：
給出錯誤（在 BfgMiner 中）：
usb_devinfo_scan: Error opening device: LIBUSB_ERROR_NOT_SUPPORTED在 CgMiner 中，它給出：

CgMiner和BfgMiner都****沒有檢測到任何設備。
cgminer 的 FPGA 和 ASIC 支持最初取自BFGMiner。由於 GPU 挖礦的維護者對 GPU 挖礦的過時感到不滿，他們分叉了該項目並最終（糟糕地）重寫了 FPGA/ASIC 驅動程序。你正在看到它的影響。
BFGMiner 繼續維護原始（工作）驅動程序，但您需要刪除 Zadig/WinUSB 驅動程序並安裝由 Silabs 提供的官方 CP210x 驅動程序。（CP210x 是 Block Erupters 使用的晶片）
